Cross layer protocol for power management in wireless sensor networks

Abstract

Wireless Sensor Networks characterize a novel paradigm for the twenty first century for the wireless technology that s grows in the numerous fields of engineering WSNs contain tiny low power autonomous devices deployed randomly in highly distributed networks Capability of such sensor in the wireless network is to meet the complex application demands So in WSNs the resource constraints are due to limited power newlinesupply memory processing capability bandwidth and unreliable wireless link etc The power management is a very important agenda within the WSNs to restrict battery supply with inadequate computational capabilities To elongate the communication of nodes the power consumption should be minimized Consequently several protocols are proposed but so far no such protocol proved to be energy efficient and cost effective to enhance the network life time of sensor nodes within the wireless sensor networks Thus the challenge of power management is to implement a cross layer design instead of conventional layer design newline
