Wireless Sensor Networks (WSNs) in delay and reliability critical environments is highly desired due to their unique advantages such as low cost, ease of deployment and redundancy. QoS routing is an imperative research issue in wireless sensor networks, especially for mission-critical monitoring and surveillance systems which needs timely and reliable data provides. As wireless communication gains popularity, significant research has been devoted to supporting real-time transmission with stringent Quality of Service (QoS) requirements for wireless applications. At the same time, a wireless hybrid network that integrates a mobile wireless ad hoc network (MANET) and a wireless infrastructure network has been proven to be a better alternative for the next generation wireless networks. By directly adopting resource reservation-based QoS routing for MANETs, hybrids networks inherit invalid reservation and race condition problems in MANETs. How to guarantee the QoS in hybrid networks remains an open problem. In this paper, we propose Zone Routing Protocol (ZRP) to enhance the QoS support capability of hybrid networks. redundant data to further improve the transmission QoS. Particle swarm optimization (PSO) based effective clustering in wireless sensor networks is proposed. To introduce a PSO, GSA and algorithms to achieve high QOS performance in network Analytical and simulation results based on the random way-point model and the real human mobility model show that ZRP can provide high QoS performance in terms of overhead, transmission delay, mobility-resilience, and scalability. This project is simulated using NS-2 simulator.
