Z-MAC AN ANALYTICAL MODEL FOR WIRELESS SENSOR NETWORKS

This paper presents an analytical model for estimating throughput and energy consumption in Z-MACprotocol for Wireless Sensor Networks. The analytical design includes transmission power control andtransmission of frames through one hop, two hop and multi hop. Proposed model reduces collision underlow contention level as well as high contention level with the use of explicit contention notification. Theproposed protocol has been simulated using MATLAB. The simulations reveal better results for throughputand energy consumption of the proposed model as compared to Z-MAC protocol.
