Localized quality of service routing protocol with service differentiation for wireless sensor networks

Abstract

In this paper, we propose a new localized quality of service routing (LQSR) protocol with service differentiation, for wireless sensor networks. Reliability, real time and energy efficient data forwarding are considered in proposed routing protocol. LQSR uses modular design architecture wherein different units operate in coordination to provide multiple QoS services. Data requirements are made visible to the framework using two bits in the packet header. Simulation results show that the protocol is efficient regarding QoS parameters and has significant improvements over several geographical and QoS-based routing protocols.
