Wireless sensor network is typically used to detect and monitor various types of objects in real-time monitoring area in which security is one major challenge. Evaluation of nodes' trust is proven to be an effective solution of improving security, supporting decision-making and nodes collaboration in both wired and wireless networks. However, existing approaches of trust management emphasize mostly...
Wireless sensor network (WSN) hierarchical routing protocols meet the efficient communication of a large-scale network. However, many of them cannot guarantee the optimum choice of the cluster heads because of the lack of comprehensive consideration of the remaining energy of nodes, the distribution within a cluster and the distribution among clusters in the process of choosing the cluster heads....
In view of the compromise between overhead and performance, this paper proposes a MAODV-X multicast routing protocol by incorporating the excellence of Explicit Multicast with the multicast-tree based routing protocol and stable link repair in Ad Hoc network, which simplifies the MAODV multicast trees by establishing the specific routing table in intermediate nodes in order to reduce the control overhead,...
We present a novel mobile Ad Hoc networks routing protocol called state-aware routing protocol, in which more QoS metrics are taken into account during the route discovery, to decrease the end-to-end delay and transmission cost. When the source initiates a RREQ message, the forwarded nodes require considering the information of energy, mobility and congestion state, hence the destination would determine...
AODV routing protocol is a classical protocol in Ad Hoc network. The scientists have already conducted the extensive research. In order to perfect the protocol, an improved protocol LAODV is proposed in this paper, which has two improvements. One improvement is that LAODV involves a delayed algorithm based on node state. It adopts a novel delayed broadcast scheme which combines the shortest route...
For the problem in the route discovery process of AOMDV route protocol: lacking congestion control leads to the inappropriate main path selected by source node in many cases, this paper proposes an improved protocol which is based on the traffic load and location information of the network. In the route discovery process, the relay node adopts a delay algorithm before broadcasting RREQ message. So...
In a 802.11 based mobile ad hoc network (MANET), the routing protocol may wrongly assume that a route is broken due to temporal packet loss in connectivity arising from multiple packet collisions, which we term as a false route breakage. In this paper, we investigate the impact of false route breakages in MANETs. It is found that false route breakage is dependent on the size of packets transmitted...
