Performance analysis of FMAC in wireless sensor networks

The set of different sensor nodes randomly deployed in sensor area to capture the environmental changes. Sensor nodes are working with specific routing and MAC Protocols in the network. Performance of the network is depends upon the network traffic and congestion in the network. Throughput, latency, loss ratio, delivery ratio, energy consumption, reliability are the QoS of the sensor network that has to considered for performance of WSN. In this paper performance of the different MAC protocols like CSMA, TDMA, 802.15.4 and FMAC for different node density is included. Effect of traffic and congestion on performance of the network is also tested. Behavior of different MAC for heavy traffic load and congestion is checked. Results are taken using NS2 simulation tool for various QoS in WSN.
