In this paper, we study distributed approximation algorithms for fault-tolerant clustering in wireless ad hoc and sensor networks. A k-fold dominating set of a graph G = (V, E) is...
The IEEE 802.11 Medium Access Control (MAC) protocol has inherent weakness of channel wastage while operating a Mobile Ad hoc Network (MANET). In this paper, we therefore propose s...

Ad-hoc networks enable mobile devices to communicate without any fixed infrastructure. While reliable multicasting has been identified as a key application in this context, we a...
In a wireless ad hoc network, the main issue of a good broadcast protocol is to attain maximum reachability with minimal packet forwarding. Existing protocols address this issue by...
