Improved Approximation Algorithms for Maximum Lifetime Problems in Wireless Networks
A wireless ad-hoc network is a collection of transceivers positioned in the plane. Each transceiver is equipped with a limited battery charge. The battery charge is then reduced a...

Dynamic Jamming Mitigation for Wireless Broadcast Networks
—Wireless communications are inherently symmetric; that is, it takes an attacker the same amount of power to modulate a signal as it does for a legitimate node to modulate the sa...

Performance of group communication over ad-hoc networks
We study the performance of reliable and unreliable allnode broadcast over ad-hoc networks that use contentionbased channel access. To obtain analytical results while preserving h...

Approximation algorithms for longest-lived directional multicast communications in WANETs
Several centralized and distributed algorithms have been recently proposed to maximize the multicast lifetime for directional communications in wireless ad-hoc networks. Their per...
