Base station positioning in Wireless Sensor Networks
Sukhkirandeep Kaur, Roohie Naaz Mir · 2016
Increased demand of Wireless Sensor Networks (WSN) in various applications has made it a hot research area. Several challenges imposed which include energy conservation, scalability, limited network resources etc. with energy conservation being the most important. Processing, sensing and communication consumes node's energy with communication being the most energy intensive task. A lot of energy is consumed in communication when Base Station is placed far from sensing area. Strategic positioning of Base Station (BS) helps in achieving energy conservation, increasing throughput and reducing delay. This paper discusses performance of the network for different BS positions. Ad-hoc On Demand Distance Vector Protocol (AODV) and Destination sequenced distance vector Protocol (DSDV) are selected to demonstrate the performance. Number of nodes is varied and performance is evaluated on basis of Packet Reception ratio (PRR), average delay and average energy. Comparison of these protocols is discussed based on above parameters.
