Enhanced approach for wireless sensor network based on localization, time synchronization and quality of service routing

Recent technological advances have enabled the development and increasing deployment of low-cost, low-power, and multi-functional sensor networks. They are multifunctional sensor nodes with varied sensing capabilities. They find application over a diversified spectrum of domains on the large scale to domestic security, patient health care defense, industrial, agriculture etc. on the small scale. Their specification and requirements do vary accordingly as some multimedia based application tolerate accuracy .but cannot afford to lose grounds on speed and defense applications require precision and timeliness. Health care systems require high reliability and fast reporting whenever certain event of reference values being crossed occurs. Certain other sensing networks can afford to go on and off alternating as they need to conserve energy. Hence, there are set of criteria to be satisfied from the point of view of localization, Time Synchronization and Service guarantees on specific quality parameters. In this work a protocol is proposed, that considers localization, time synchronization and Quality of service based routing. The designed protocol is simulated using NS-2.34 and comparative analysis is performed on parameters with two existing protocols namely Energy efficient and Quality of service based routing protocol for Wireless Sensor Networks and Location aware event driven multipath routing in Wireless Sensor Networks.
