Abstract—Directional antennas are expected to provide significant improvements over omni-directional antennas in wireless ad hoc networks. Directional MAC protocols, however, int...
In ad-hoc networks, autonomous wireless nodes can communicate by forwarding messages for each other. For routing protocols in this setting, it is known that a malicious node can p...
We examine the performance of the TCP protocol for bulkdata transfers in mobile ad hoc networks (MANETs). We vary the number of TCP connections and compare the performances of thr...
We address the problem of secure and fault-tolerant communication in the presence of adversaries across a multihop wireless network with frequently changing topology. To effectivel...
Because of the heterogeneity in radio transceiver capabilities and influence of surroundings, unidirectional links arise in wireless mobile ad-hoc networks. Since most of existin...
