Oppurtunistic routing algorithm for hidden node collision avoidance and energy efficient wireless sensor network

摘要

Energy utilization has been a major factor in deciding the efficiency of ubiquitous wireless sensor networks. Since most of the wireless nodes are powered by battery an effective algorithm is necessary to use the limited resource effectively. Data collision occurs in Intra-clustered network due to the use of Omni-directional antennas and any introduction of new node in to the network. In this paper, we use an opportunistic routing algorithm so that the energy of nodes are utilized effectively, thereby increasing network lifetime. The data collision is minimized by use of directional antenna and beam scanning technique, to scan for cluster heads, which will minimize data collision in the network, which also indirectly improves network lifetime.
