An Improved Algorithm for Flow-Based QoS Routing Protocol in WSN
This paper is to solve the problem of route resources waste in flow-based QoS routing protocol for WSN. Competition for limited resources will rose when there are two or more real time data flows between same source node and destination node, Variable “port is set to identify different real time data flows before, which also leads to waste of route resources. Thus we set a time variable called Ptime to determine the life time of port, which can reduce idle time of each route path. Simulation results show that this algorithm can reduce route waste and improve the QoS of routing protocol.
