In this paper we devise efficient optimization techniques to find optimal routing and scheduling policies for wireless ad hoc networks in the presence of multi-user interference and cooperative transmissions. Our focus is to assess the impact of interference among distinct data flows on optimal routing paths and related transmission schedules. In our reference scenario, all nodes have a single antenna...
One of the attractive features of the wireless mesh network is its ability to scale to larger covered area by simply adding more wireless routers. This scalability increases the average number of hops from source to destination and hence it may affect the network performance in terms of delay and throughput. Many solutions have been proposed for wireless mesh networks. Among them the 802.11s proposes...
Due to the high overhead characteristics of wireless mesh network, the call capacity of VoIP is dramatically degraded. In the paper, the Aggregation Aware Routing with Path Separation (AAR-PS) protocol has been proposed. The protocol are designed by combining and engineering several techniques: packet aggregation, multi-path routing and event-triggered rerouting. The experiment results reveal that...
Voice over IP (VoIP) over a wireless mesh network (WMN) is a killer application candidate of the next generation services over wireless and mobile network infrastructure. Yet, the routing and transport efficiencies in consideration of specific attributes of WMNs have been little emphasized. Distinctively from conventional networks, the major traffic pattern of WMNs is anycast (one-to-one-of-many)...
Initial entry during deployment requires tactical networks supporting voice, video, and data requirements to be established quickly given little existing telecommunication infrastructure. Wireless mesh networks using contention-based medium access control (MAC) appear to be an easy off-the-shelf solution, but their performance is lacking for support of such diverse high-bandwidth low-latency requirements...
In mesh networks, various types of routing matrix are applicable. This document proposes a routing methodology, which makes use of the ETR (Expected Transmission Rate). The ETR is based on a load balancing metric contingent on the linked bandwidth of each integrated node. This routing methodology can be applied when selecting a relay node based on the present link efficiency between the available...
