TCP-aware Source Routing in Mobile Ad Hoc Networks
نویسندگان
چکیده
Temporary link failures and route changes occur frequently in mobile ad hoc networks. Since TCP assumes that all packet losses are due to network congestion, TCP does not show satisfactory performance in ad hoc networks. In this paper, we propose a simple and new mechanism called TSR, TCP-aware Source Routing, which can improve TCP performance in mobile ad hoc networks. By reducing the number of invalid routes, TSR minimizes TCP’s consecutive timeouts. In our simulation study, TSR achieves up to 50% TCP performance improvement without requiring any modification of TCP stack in end systems.

Energy Efficient Routing in Mobile Ad Hoc Networks by Using Honey Bee Mating Optimization
Mobile Ad hoc networks (MANETs) are composed of mobile stations communicating through wireless links, without any fixed backbone support. In these networks, limited power energy supply, and frequent topology changes caused by node mobility, makes their routing a challenging problem. TORA is one of the routing protocols that successfully copes with the nodes’ mobility side effects, but it do...
