Power Saving is one of the most critical issues for portable devices in wireless local area network as battery power is a scarce resource. The issue becomes even more severe for wireless ad hoc networks as lack of available infrastructure could mean lack of available resources for battery recharge. IEEE 802.11 provides a mechanism known as PSM (Power saving mechanism), this mechanism achieves power...
Wormhole attacks are considered as a severe security threat in multi-hop wireless ad hoc networks. In this paper, we propose an Energy-Efficient Scheme Immune to Wormhole attacks (our so-called E2SIW). This protocol uses the location information of nodes to detect the presence of a wormhole, and in case a wormhole exists in the path, it finds alternate routes involving the nodes of the selected path...
