A Novel Adaptable Routing Protocol for Wireless Sensor Networks

Routing is an important issue in WSNs with the sensor nodes having limited processing power, memory etc. In this paper we present a query-based routing protocol for a WSN that provides different classes of Quality of Service (QoS) in terms of energy-efficiency, reliability, low latency and fault tolerance for different application requirements. The algorithm has low computational overhead while guaranteeing different QoS support based on the application demand. The novelty of the proposed algorithm is the ability to provide multiple QoS support without having to reconfigure or redeploy sensor nodes. The performance of the algorithm has been evaluated by implementing it on network simulator NS-2 with 802.15.4 libraries. The results show that the algorithm gives good performance statistics for the designed QoS terms thereby satisfying the goal of the design.
