Comparative performance analysis of IEEE 802.15.4 in WSN using NS2

Wireless Sensor Networks (WSNs) are type of network which is mainly deployed to those areas where infrastructure network is unavailable and where people cannot reach easily. To those areas sensors are deployed to collect information about the environment. Since sensors are run by battery power, long time use of sensors to those remote areas, is one of the main challenges for WSN. To deal with long time use of battery power, low power consumption technique is used. IEEE 802.15.4 standardization is used for Low Rate Wireless Personal Area Network (LRWPAN). To get a lesser amount of consumption of power, few parameters of IEEE 802.15.4 are changed in our proposed strategy. At last comparison of proposed strategy and IEEE 802.15.4 is made where proposed strategy performs well for low power consumption.
