Life time maximization analysis with application to LL MAC & RI-MAC protocol in wireless sensor networks
G. Vigneshwar, T. Senthil · 2013
Wireless sensor networks plays a vital role in emerging technologies, but the major problem regarding the sensor nodes is the limited energy provided. In order to utilize the energy efficiently a MAC protocol with duty cycle mechanism is being adopted to reduce idle listening problem by periodically putting the sensors to sleep and waking up .It is important to understand which type of duty cycled MAC protocols should be chosen (synchronous or asynchronous). In this paper we propose a Markov queuing model to analyze the throughput of both synchronous and asynchronous protocols with application to LL-MAC (low latency MAC) and RI-MAC (receiver initiated MAC).
