Lifetime Analysis Using Encoding Technique in Wireless Sensor Network
Journal Title: INTERNATIONAL JOURNAL OF COMPUTER TRENDS & TECHNOLOGY - Year 2014, Vol 9, Issue 3
Abstract
The significant challenge in Wireless Sensor network is to maximize the network lifetime through minimizing energy. The monitoring area close to the Sinknode forms a bottleneck zone because of large traffic- flow which limits the network lifetime in wireless sensor network. In this paper, we introduce an encoding technique for reducing energy consumption in the bottleneck zone. An efficient communication paradigm has been adopted in the bottleneck zone by combining duty cycle and encoding technique. Energy efficiency of the bottleneck zone increases because more volume of data will be transmitted to the Sink with the same number of transmissions. Hence the lifetime of wireless Sensor network is enhanced. Life time can be analysed by considering with two scenarios of single hop and multihop.The lifetimeupper bounds have been analysed by combining duty cycle and encoding technique. The simulation results demonstrate the efficacy of proposed technique.
