In HSVAN, sensor nodes' distribution is prearranged and deployed along with the roadsides and have centralized communication channel with sensor gateway that alert drivers from dangerous conditions. However, the network dynamic imposes new challenges that should be addressed regarding appropriate routing protocols that should be implemented to disseminate the data among the nodes. In this paper, the performance of AODV and OLSR routing protocols in HSVAN adopting IEEE 802.11b and IEEE 802.11p MAC standards was investigated. The simulation scenario represents a rural environment with six nodes and one WSN gateway using the NS-3 and SUMO simulator. Simulation result shown that IEEE 802.11p achieved 9% throughput gain over IEEE 802.11b as a MAC protocol. Moreover, the AODV routing protocol outperformed OLSR by 3%, 4%, and 55% in term of throughput, packet delivery ratio, and end to end delay respectively. However, the effect of mobility high data request not been considered to imitate the real HSVAN environment.","PeriodicalId":216908,"journal":{"name":"2016 2nd International Conference on Wireless and Telematics (ICWT)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123461272","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}

Pre-launching stages are API/A process, Satellite Coordination process, Res 49 process, Notification process, and Satellite Launching process. Indonesian new government has a Nawacita program should be supported by national telecommunication infrastructure specially using satellite. Indonesian satellite market showed supply and demand gap condition, where the most of satellite usage was provided by foreign satellites. There were 34 for foreign satellites used in Indonesia that served by 15 countries. Currently, Indonesia used foreign satellite capacity is equal to 5 foreign satellites. In this paper, satellite deployment satellite model in Indonesia is developed by government investment budget that we called \"layer one\". The whole processes should follow Radio Regulations was setted up by ITU When \"layer one\" as a government function is completed and satellite capacity is ready be delivered to the users, then private companies, or government enterprises that already be selected by the government deliver that capacity. The selection of the operators could be through an auction, or others of selection method. The function of private company or government enterprises delivery satellite capacity or satellite service to their customers its called \"layer two\".

But it can lead to a worse inter-cell interference levels experienced especially by users located at the cell edge area. Soft Frequency Reuse (SFR) is considered as an effective frequency reuse scheme for inter-cell interference coordination to increase the spectrum efficiency. In this research, an LTE network will be planned at 1800 MHz using monte carlo computer simulation to examine the performance of SFR for LTE downlink transmission. We consider issues of different power ratio and various traffic loads. Both performance of cell edge users and overall cell performance are evaluated in terms of SINR, BLER, and throughput. The result of performance with SFR scheme will be compared againts the classical frequency reuse one and frequency reuse three scheme. The simulation result shows that SFR can improve the performance for the users at the cell edge. In general, SINR can be increased about four times compared with frequency reuse one and BLER can be improved up to 81,41%.","PeriodicalId":216908,"journal":{"name":"2016 2nd International Conference on Wireless and Telematics (ICWT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115862964","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}

Since received signals are contaminated by noise, such techniques are developed to calculate reflectivity accurately. Signal processing on Doppler domain is one of Fast Fourier Transform (FFT)-based method that is usually used to calculate reflectivity. Another FFT-based method that can be used to estimate reflectivity is using spectrum estimation to substitute FFT, so that the processing can be done in time domain. However, spectrum estimation requires more concern on signal modelling and filter coefficients estimation. This research compares and analyzes the performance of FFT-based spectrum estimation with Doppler domain processing. The spectrum estimation methods are based on autoregressive (AR) parametric estimation and adaptive filtering that has been well known in another application. Raw voltages on receiver are processed to estimate reflectivity. Simulation done for FMCW radar with center frequency 9.475 GHz (X-band) and typically bandwith of 5 MHz. The simulation results show that time domain signal processing using adaptive filter gives more satisfying result com pared to parametric estimation.","PeriodicalId":216908,"journal":{"name":"2016 2nd International Conference on Wireless and Telematics (ICWT)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126517699","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}

Furthermore, Fast Handover for PMIPv6 (PFMIPv6) protocol has been standardized to improve the handover performance of PMIPv6 in terms of handover latency and packet loss. The limitation of these Centralized Mobility Management (CMM) protocols (e.g., non optimal routes, single point of failure and scalability) has led to the development of Distributed Mobility Management (DMM) paradigm. DMM aims to flat the network architecture by placing the anchor entity dynamically closer to the MU. The DMM solutions can be classified into: host-based DMM, in which MU participates in IP mobility process, and network-based DMM, where IP mobility process is done in the network side without MU involvement. However, existing network-based DMM proposals rely on PMIPv6 protocol which experience high handover latency and packet loss. Thus, we present the design and operation of a proposed network-based DMM solution based on PFMIPv6. We have developed an analytical model to evaluate and compare the handover latency and the packet loss of the proposed network-based DMM solution and IETF networkbased DMM proposal.","PeriodicalId":216908,"journal":{"name":"2016 2nd International Conference on Wireless and Telematics (ICWT)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116162048","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}
