Hybrid Routing Protocol and Dynamic Delivering Scheme for MultiEvent Wireless Sensor Network

Abstract

In multievent wireless sensor networks (WSN) like smart kindergarten, forest fire alarm system, vehicle tracking system. many events have different QoS (Quality of Service) requirements such as latency, rate, reliability, etc. Most of researches in this area have just dealt with one or two QoS requirements or one QoS requirement with several priority levels, there has not been any research supported multi QoS requirements for multievent WSN. This paper proposes a novel solution to meet the new and diverse requirements for multievent WSN called CSM. By combining hybrid routing protocol and packet delivering scheme, our proposed solution enables multievent WSN support multiple QoS requirements such as latency and reliability. Simulation results show that, with multiple QoS requirement events simultaneously occurring in the network, the proposed scheme brings better network performance in terms of latency (reduces 20% delay) for lower latency requirement events and lower packet error rate for higher reliability requirement events than other coexisting events.
