Design Framework of Collision Avoidance and Energy Efficient MAC for MWSN

Getsy S. Sara and Sridharan D.

Abstract—Mobile Wireless Sensor Network (MWSN) adds new design dimension to the existing MAC protocols due to the mobility of nodes. Collision probability and communication power consumption is increased in MWSN. In this paper, a hybrid MAC protocol which minimizes collision and achieves energy efficiency is proposed. Clustering of mobile nodes is done here and scheduled slots are provided by fusion nodes to each mobile sensor node during intra precinct communication. Contention based communication with strobed preamble is applied for inter precinct communication between gateway nodes. It avoids collision probability by applying RTS-CTS mechanism in tandem with data fragmentation. By simulating with OMNET++, the efficacy of this protocol can be evaluated.

Index Terms—Collision avoidance, energy efficiency, MAC protocol, mobile wireless sensor network.
