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