Limited Contention Scheme(LCS) to reduce collision in LR-WPAN

Abstract

Data collision in LR-WPAN(Low Rate Wireless Personal Area Network) causes retransmission of which energy consumption may reduce life of the entire network Furthermore LR-WPAN is very sensitive to collision as it has relatively fewer frequencies of back-off retries. LCS(Limited Contention Scheme) suggested in this study is a way to transmit data by certain groups of the total nodes so that it can reduce possibilities of data collision and retransmission by decreasing the number of competing nodes. As a result LCS can increase a throughput and the life of the entire network. As using LCS in designing LR-WPAN in the future can extend battery life, LCS can be useful in any application that requfres low energy consumption. © 2009 IEEE.
