A key element is the usage of the battery on mobile networks, and the performance of an ad-hoc network can be affected by mobile nodes leaving the network due to lack of battery power.
By increasing the speed of mobile nodes, nodes leave their vicinity more rapidly, resulting in disrupted clusters and more frequent reclustering, which increases the energy consumption in KoN-MAC.
When mobile nodes voluntarily leave the original group to join the new group (i.e., sending a leaving request) or when the mobile nodes roam to the outside of their adjacent field and are detected in other AFs, which leads to the essential changes of the group members, it will perform the key updating process.
Similarly, in [7], the actual sample reputation score, Qn(c i ), is calculated by the mobile node upon entering or leaving a given network in the same fashion as the Qth.
Managing mobile node mobility in target tracking applications in mobile sensor networks is addressed in [17].
We describe secure schemes for a mobile node to initiate, join and leave a cluster.
In ad hoc networks, mobile nodes join or leave networks dynamically, necessitating that the system performs group key reconstructions frequently.
A mobile node can probabilistically move straight, turn right, or turn left at the intersections with probabilities of 0.5, 0.25, or 0.25, respectively.
In this paper we introduce and analyze an architecture called Transport Layer Mobility that allows mobile nodes to not only change their point of attachment to the Internet within a corporate domain, but also to control which network interfaces are used for the different kinds of data leaving from and arriving at the mobile node.
