Constructing minimum-energy broadcast trees in wireless ad hoc networks
In this paper we assume that a multihop wireless network (also called a wireless ad hoc network) consists of nodes whose transmitting powers are finitely adjustable. We consider t...

Detecting MAC Layer Back-off Timer Violations in Mobile Ad Hoc Networks
In IEEE 802.11 based ad hoc networks, by simply manipulating the back-off timers and/or wait times prior to transmission, malicious nodes can cause a drastically reduced allocatio...

Faster Deterministic Gossiping in Directed Ad Hoc Radio Networks
Abstract. We study the gossiping problem in directed ad-hoc radio networks. Our main result is a deterministic algorithm that solves this problem in an n-node network in time O(n4/...
