QoS routing algorithm research based on the node occupation degree control for wireless sensor networks

Abstract

This paper analyses the problem of the data structure of the AODV algorithm, routing setup and path finding. In the multi-tasking environment for wireless sensor networks, we propose NOC-AODV(Node Occupation Control AODV)algorithm that using a node occupation-degree to avoid the impropriated nodes, In the algorithm, according to judge the value of the node occupancy degree, it can determine the node's action in the WSN. Using NS platform, we make some simulation in the multi-tasking environment. NOC-AODV algorithm reduces 20% about the delay, cut down 50% about the packet loss rate and eliminate the massive useless Hello packet compared with AODV algorithm. © Springer-Verlag Berlin Heidelberg 2012.
