Recent development in the field of Wireless communications and electronics has enabled the deployment of Wireless sensor Networks (WSNs) in an expanding variety of applications. Significantly, wireless communications have demonstrated profound significance in a variety of applications ranging from military to health applications and from home to industry. In WSNs, a major goal is conserving the sensor...
In multihop networks such as mobile ad hoc networks (MANETs), a node can misbehave by selfishly dropping others' packets to save battery life. This selfishness or misbehaviour can disrupt the whole network functionality and can severely degrade network performance. Reputation based models have been developed to discourage node misbehaviour. However, these models are vulnerable to whitewashing attacks...
In wireless sensor networks constructed from battery driven nodes, it is difficult to supply electric power to the nodes. Because of this, the power consumption must be reduced. To cope with this problem, clustering techniques have been proposed. EACLE is a method that uses a clustering technique. In EACLE, the route selection is executed independently after the CH (Cluster Head) selection. These...
Wireless sensor networks are constituted of a large number of tiny sensor nodes randomly distributed over a geographical region. In order to reduce power consumption, nodes undergo cycles of active-sleep periods that reduce their ability to send/receive data. Aim of this paper is to analyze the reliability of a battery-powered sensor node with active-sleep cycles considering both linear and non linear...
