Multipath routing has been proved effective in mobile ad-hoc networks (MANETs) for coping with link failures resulting from node mobility. In wireless mesh networks (WMNs) where routers are generally static, the traffic carried by the backup paths may adversely impact other flows and the multicast group itself, because these paths increase the number of transmissions and thus the level of interference...
Because of the lack of infrastructure in mobile ad hoc networks (MANETs), their proper functioning must rely on co-operations among mobile nodes. However, mobile nodes tend to save their own resources and might be reluctant to forward packets for other nodes. In this paper, we address the charging and accounting problems in MANETs. We develop a theoretical game model that offer advice to a central...
We present a simulation-based study of the impacts of different types of attacks in mobile ad hoc networks (MANETs). We consider three common types of attacks: blackhole attack, jellyfish attack and neighbor attack. Specifically, we study how the number of attackers and their positions affect the performance metrics of a connection such as packet delivery ratio, throughput, end-to-end delay, and delay...
Multi-channel multi-radio (MCMR) wireless mesh networking is an emerging technology that enables high-throughput networking capability using multiple channels and multiple radios per mesh router. Traditional multicast routing algorithms such as shortest path trees and minimum Steiner trees do not consider the wireless broadcast advantage or the underlying channel assignments (i.e., channel diversity)...
