Supporting high mobility is essential to mobile ad hoc networks in a wide range of emerging applications such as vehicular networks. Communication links of an established communication path that extends between source and destination nodes are often broken under a high mobility environment. Although a new communication route can be established when a break in the communication path occurs, repeatedly...
Video transmission over ad hoc networks is more challenging than over other wireless networks. The wireless links in an ad hoc network are not very error resilient and can go down frequently because of node mobility, interference, channel fading, and the lack of infrastructure. Moreover, typical video applications may need a higher bandwidth and higher reliability connection than that provided by...
In highly mobile pure ad-hoc wireless mesh networks, fast rerouting within low routing discovery delay is a mandatory requirement for routing algorithm to support interactive applications such as VoIP. Also, the communication overhead should be thwarted when networks grow to a large scale. We propose a tree-based routing algorithm - TBRA to facilitate such two goals. On one hand, TBRA has very low...
One of the most important challenges in mobile ad hoc networks is to use an efficient and dynamic routing protocol, as the nodes can move randomly, which requires the routing protocol to respond quickly to the network topology change. In this paper, a new hybrid routing protocol, based on a reactive AODV routing, is introduced. It follows the proactive approach for some special nodes in some interval...
The task of finding and sustaining routes in mobile ad-hoc networks (MANETS) is an important factor in determining the efficiency of any MANET protocol. MANET characteristically comprises of wireless mobile hosts whose communication with each other is devoid of any fixed infrastructure. Absence of fixed infrastructures and host mobility thus constitute frequent unpredictable topological views. Positional...
There is an ambiguous opinion in the literature on whether multi-path routing offers significant merit in terms of a networkpsilas performance. The one camp supports the belief that multi-path routing is indeed advantageous compared to single-path counterparts and the other contends that the improvement is not significant, if at all. For the performance evaluation of the two counterparts, Dynamic...
In recent years, on-demand multipath routing protocols have been a key research area in mobile ad-hoc networks. Such protocols are crucial in providing resilience to route failures and to successful load balancing. Previous work shows that on-demand multipath routing protocols achieve lower end-to-end delay, routing overheads and higher goodput under certain scenarios when compared to traditional...
