IEEE standard 802.11for WLAN has been meeting out the communication prospect in any organization. A Mobile Adhoc Network (MANET) is defined as the collection of independent mobile nodes that can communicate with each other via radio waves. In mobile ad hoc networks, the key distribution is the main constraint in data transmission. For secure group based data transmission in the distributed environment, a secret key has to be shared among the users for the secured data transmission. For establishing efficient key distribution and management, a novel dynamic group secret key management is introduced. For secure data communication, a group secret key must be shared by all group members. This group secret key should be updated when the existing group members are leaving the network or new members are entering into the existing network. In this paper, we propose an efficient group secret key agreement procedure called Key distributed management protocol which is based on Elliptic curve cryptography. Here the model of scheme is to divide a large group into several subgroups, each maintaining its subgroup secret keys to control the subgroup and managing many subgroups using KEY escrow Based Elliptic Curve Cryptography management algorithm. In KEYBECC, we develop two protocols namely, Subgroup Secret Key Generation (SSKG) and Group Secret Key Generation (GSKG) based on ECDH for subgroups and outer groups respectively. These subgroup keys and group keys should be changed when there are membership changes (such as when the current member leaves or the new member joins). In the paper, we propose and implement a new methodology for dynamic key distribution. We simulate the environment for mobile networks with the proposed algorithm named Enhanced Key Escrow Based ECC (KEYBECC) with comparison of the traditional algorithms prevailing for MANETs. Compared to the existing approaches, KEYBECC demonstrates advanced key distribution features with better throughput efficiency without compromising on communication overhead and storage cost. From the simulation analysis, the proposed dynamic group key agreement protocol performs well for the distributed key establishment problem in mobile ad hoc network in terms of throughput efficiency, communication overhead and storage cost.","PeriodicalId":195637,"journal":{"name":"InfoSciRN: Other Information Networks (Sub-Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130781906","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}

{"title":"Energy Efficient Direction Based Routing Protocol for WSN","authors":"Syed Mohd Ali, Syeda Gauhar Fatima, Syeda Kausar Fatima, Syed Abdul Sattar","doi":"10.34218/IJARET.10.2.2019.013","DOIUrl":"https://doi.org/10.34218/IJARET.10.2.2019.013","url":null,"abstract":"Energy consumption is one of the limitations in Wireless Sensor Networks (WSNs). The routing protocols are the hot areas to address quality-of-service (QoS) related issues viz. Energy consumption, network lifetime, network scalability and packet overhead. The key issue in WSN is that these networks suffer from the packet overhead, which is the core cause of more energy consumption and damage the QoS in sensor networks. In WSN, there are several routing protocols which are used to improve the performance of the network. Out of those protocols, Dynamic Source Routing (DSR) protocol is more appropriate in terms of small energy density, but sometimes when the mode of a node changes from active to sleep, the effectiveness decreases as the data packets needs to wait at the initial point where the packet has been sent and this increases the waiting time and end to end interruption of the packets which leads to increase in energy consumption. Our problem is to recognize the dead nodes and to choose another suitable path so that the data transmission becomes smoother and less energy gets preserved. In order to resolve these issues, we propose directional transmission-based energy aware routing protocol named as PDORP. The proposed protocol PDORP has the characteristics of both Power Efficient Gathering Sensor Information System (PEGASIS) and DSR routing protocols. In addition, hybridization of Genetic Algorithm (GA) and Bacterial Foraging Optimization (BFO) is applied to proposed routing protocol to identify energy efficient optimal paths. The performance analysis, comparison through a hybridization approach of the proposed routing protocol gives better result comprising less bit error rate, less delay, less energy ingesting and better throughput which leads to better QoS and prolong the lifetime of the network. Moreover, the Computation Model is adopted to evaluate and compare the performance of the both routing protocols using soft calculating techniques.","PeriodicalId":195637,"journal":{"name":"InfoSciRN: Other Information Networks (Sub-Topic)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129421374","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}
