—The concept of cooperative retransmission in wireless networks has attracted considerable research attention. The basic idea is that when a receiver cannot decode a frame, the r...
Most ad hoc mobile devices in wireless networks operate on batteries and power consumption is therefore an important issue for wireless network design. In this paper, we propose an...
A wireless ad hoc network is formed by a group of wireless hosts, without the use of any infrastructure. To enable communication, hosts cooperate among themselves to forward packet...
In wireless ad hoc networks, all its nodes behave as routers and take part in its discovery and maintenance of routes to other nodes. Thus, the presence of selfish or malicious nod...
