Traditional firewalls have the ability to allow or block traffic based on source address as well as destination address and port number. Our original ROFL scheme implements firewalling by layering it on top of routing; however, the original proposal focused just on destination address and port number. Doing route selection based in part on source addresses is a form of policy routing, which has...

Xiaohui Liang, Xu Li, Qinghua Shen, Rongxing Lu, Xiaodong Lin, Xuemin Shen, and Weihua Zhuang, “Prediction to Enable Secure and Reliable Routing in Wireless Body Area Networks”, Proceedings of IEEE INFOCOM’12, pp. 388-396, 2012. In this paper, we propose a distributed Prediction-based Secure and Reliable routing framework (PSR) for emerging Wireless Body Area Networks (WBANs). It can be integra...

In this paper the mobile ad-hoc networks where there is no fixed infrastructure the mobile nodes are highly dynamic mobility. Due to mobility of node cased increasing over head and also require more energy consumption. , in mobile ad hoc network major challenging issue is energy and network overhead because of mobile nodes have limited energy source which are operated with only DC source. The e...

We study routing schemes for Disruption Tolerant Networks (DTNs) where transmission bandwidth is scarce resource. In such a setting, a key issue is how to schedule the transmission of packets under limited bandwidth to optimize performance. Such a scheduling consists of source control (i.e., source nodes choosing a routing scheme) and the local transmission scheduling performed by each node. Ex...

In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the source station, which causes more congestion and massive reduction in the overall network throughput. The netw...

-Wireless Mesh Networks (WMNs) are the set of wireless nodes that can communicate with each other and forwarding each other’s packets. WMNs are multi-hop networks consisting of routers, gateways and mobile nodes, they aim at guarantee connectivity. They act as a key technology for next generation WMNs due to their low cost and relative ease of deployment they are an attractive paradigm and are ...

In this study a multicast routing algorithm has been developed for faulty hypercube parallel processing system using cube algebra. Without any restriction to the number of the faulty nodes, the routing from the source node to the destination node is implemented minimally. The developed routing algorithm has been visually simulated via prepared data routing simulator program. It has been observe...

In this paper, we propose a novel routing algebra system to investigate greedy routing in geographic routing. Four important algebraic properties, respectively named mutex, transition, source independence and strict preference, are defined in this algebra system. Based on these algebraic properties, the necessary and sufficient conditions for the loop-free and consistent compatibilities of gree...

This paper gives a survey in QoS Routing Architecture implemented by Dijkstra’s algorithm. The performance of QoS Routing architecture is evaluated by made a comparison between the Shortest Path Routing and QoS one. A very important feature in QoS routing are the conditions for elimination of starvation. Experimentally we have evaluated the number of packets delivery from source node to destina...

An ad-hoc network is a spontaneous network that emerges when two or more wireless nodes pledge to help each other. As the wireless range of these nodes is usually limited so each node commits to forward the packets on behalf of its neighbours in accordance with a predefined routing protocol. Dynamic Source Routing (DSR) is one of the widely used routing protocols that is currently undergoing ex...
