There have been studies regarding various combinations of routing protocols that defines the efficient pathway to interconnect the smart devices. Proactive, reactive and hybrid routing protocols are the three types of routing protocols defined on the basis of route discovery. The core objective of this paper is to provide a comparative performance analysis on the routing protocols using a ViSim tool that integrates the Ns2 simulator. This tool focus on MANET (Mobile Ad-Hoc Network) protocols for proactive - DSDV (Destination-Sequenced Distance-Vector Routing) and reactive - DSR (Dynamic Source Routing) and ADOV(Ad-hoc On-demand Distance Vector). Throughput, Goodput (packets and packet size) and Routing load (packets and packet size) are the parameters to make comparison between the routing protocols for performance analysis. This tool can be modified in the future for better analysis of different routing protocols.","PeriodicalId":254711,"journal":{"name":"2021 International Conference on Computational Intelligence and Knowledge Economy (ICCIKE)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121943307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Food delivery apps have become popular not only in the U.A.E, but worldwide, as people take precaution through social distancing and quarantine in the hopes of curbing the spread of the coronavirus. Restaurant owners have put delivery services on the spotlight, urging them to cut down their commission rates as they are negatively implicating their businesses. Third-party services have been known to take commissions out of the restaurant owners they partner with. However, restaurant owners complain that these rates have increased over the years, with zero reductions especially with slow business as a result of the pandemic. Delivery apps have not waivered their commissions, charging as high as 35% per order, which is not inclusive of a delivery fee for the consumer. The food industry is requesting third-party companies for a 10% reduction for each order, for them to be able to make ends meet. The paper encloses a survey conducted on restaurants in the U.A.E to assess the impact of commission rates by these delivery apps. The results showed that the restaurants are struggling to keep afloat, a factor that is bound to affect the employment of many staff members in these hotels. The paper, therefore, outlines the impact of these commission rates among other charges on restaurants and other food businesses in the United Arab Emirates. .","PeriodicalId":254711,"journal":{"name":"2021 International Conference on Computational Intelligence and Knowledge Economy (ICCIKE)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122582082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on communication with transportation infrastructures, the traffic information like Signal Phase and Times (SPaT) of traffic signals or stop time of bus stations over the entire route will be known precisely in advance. A spatial PHEB velocity optimization formulation with communication to traffic information is proposed to minimize the energy consumption or travel time. Two procedures are used for optimizing the objective, first, a State-of-Charge (SOC) curve is obtained from optimization with known road conditions for replacing empirical data to avoid the heavy computational duty of solving three-dimension dynamic programming. Then the optimized velocity profiles are calculated via a two-dimension dynamic programming model. Finally, the simulation results validate the energy savings and time savings of the proposed velocity planning strategy.","PeriodicalId":254711,"journal":{"name":"2021 International Conference on Computational Intelligence and Knowledge Economy (ICCIKE)","volume":"13 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124996850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The protection of salt marshes below rapid sea-level rise (SLR) usually includes the survival of underdeveloped moorlands of marsh betrayal zones with which wetlands can transition. Optimal conservation planning of this kind includes details on forest protection's potential benefits and the cost of worthy sites for migrating marshes in specific areas. Although available content is known within the literature on marsh benefits, the prior study offers little visibility into the related costs of land protection. Discrete mathematics shows that a largish task requires the success of issue data. Computers are ineffective to overcome even moderately sized hiccups without reliable information to direct them, considering their pace in performing inquiries. Three tests are proposed to classify the information needed for an effective search: (1) ligneous particulars that measure the difficulty of finding a goal using a random search; (2) physiologic particulars that estimate the challenge of obtaining a goal once a search has some of the problem-relevant information; and (3) active particulars that distinguish the differences among specific particulars. The results show the conservation planning perspective that models can provide and help review simplistic proxies to estimate the cost of conservation of land desirable for marsh migration. This paper establishes a technique focused on these knowledge measures to gauge the efficiency with which efficient search is enabled by dilemma information. This technique is then extended to numerous search instruments commonly used in the evolutionary quest.","PeriodicalId":254711,"journal":{"name":"2021 International Conference on Computational Intelligence and Knowledge Economy (ICCIKE)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128874014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developers adapt our environment to learning maximum entropy policies, leading to a simple Q-learning service, which communicates the global optimum through a Boltzmann distribution. We could use previously approved amortized Stein perturbation theory logistic regression rather than estimated observations from that distribution form to obtain a stochastic diffusion network. In simulated studies with underwater and walking robots, we confirm that the entire algorithm's cost provides increased exploration or term frequency that allows the transfer of skills between tasks. We also draw a comparison to critical actor methods, which can represent on the accompanying energy-based model conducting approximate inference.

In a misleading game, nearly all cutting-edge research techniques, including those qualify superstition yet, even with self-recompenses, which achieves enhanced outcomes in the sparse re-ward game, often easily collapse into global optimization traps. We are introducing another exploration tactic called Maximum Entropy Expand (MEE) to remedy this shortage (MEE). Based on entropy rewards but the off-actor-critical reinforced learning algorithm, we split the entity adventurer policy into two equal parts, namely, the target rule and the adventure policy. The explorer law is used to interact with the world, and the target rule is used to create trajectories, with the higher precision of the targets to be achieved as the goal of optimization. The optimization goal of the targeted approach is to maximize extrinsic rewards in order to achieve the global result.
