In virtue of its widespread application scenarios, especially in battlefield communication, disaster rescue, satellite and deep-space transmission, Delay-disruption Tolerant Network (hereinafter referred to as DTN) has become one of the most attractive focuses in research for future Internet. Due to the intermittent connectivity, mobility of nodes, signal interference, jamming in DTN, there exist...
A wireless ad hoc network (WANET) is a collection of wireless terminals that communicate with each other without predetermined topology. Since WANET devices are power-limited, network protocols should be designed to prolong the battery lifetime of these devices. In this paper, we propose a cross-layer integration approach for power efficient routing protocol. The proposed cross-layer integration between...
Wireless sensor networks consist of a number of small wireless sensor nodes which take measurements and transmit them over wireless links. As wireless sensors are resource constrained, the usage of energy and memory must be done wisely to increase the lifetime of nodes. It is also necessary to deliver data reliably to make any application more useful to the end user. A reliable and lightweight routing...
In vehicular ad hoc networks (VANETs), a source node must rely on other nodes to forward its packets on multi-hop routes to the destination. Trust propagation is the principle by which new trust relationships can be derived from pre-existing trust relationship. Modeling for trust propagation is a fundamental block in an ad hoc environment. The main contribution of this work is a novel scheme to enhancing...
Vehicular ad hoc networks (VANETs) allow communications over sequences of vehicles with radio devices. On such a network, there are many possible applications such as traffic jam warning, collision warning, parking lot reservations, camera picture feed etc. There have been quite a few results in the area seeking for a fast and reliable communication protocol due to their potential. VANETs, however,...
MANET (mobile ad hoc network) is a mobile multi-hop, wireless self-organized distributed network. This paper introduces the concept and characteristics of MANET, gives a general survey of research on local repair for MANET and proposes a new local repair scheme based on link breaks in order to make up the deficiency of the existing local repair schemes. The improved local repair scheme concerns about...
Routing in MANETs becomes a more sophisticated issue especially when a certain QoS requirement is to be satisfied. One of the most important QoS metrics is end-to-end reliability. Multi-path routing can be considered as an effective method to support end-to-end reliability. However, the path discovery in current multi-path routing algorithms considering reliability relies mostly on local link availability...
