Mobile sensor networks rely heavily on inter-sensor connectivity for collection of data. Nodes in these networks monitor different regions of an area of interest and collectively present a global overview of some monitored activities or phenomena. A failure of a sensor leads to loss of connectivity and may cause partitioning of the network into disjoint segments. A number of approaches have be...

Many routing protocols have been designed for Ad Hoc networks. However, most of these kinds of protocols are not able to react fast enough to maintain routing. In the paper, we propose a new protocol that repairs the broken route by using information provided by nodes overhearing the main route communication. When links go down, our protocol intelligently replaces these failed links or nodes wi...

Aiming at the team-based mobile ad-hoc networks (MANETs), this paper proposes a main-route mechanism by the mobility difference degree of nodes and a backup route mechanism by the nodes stability. In this paper, the whole network is divided into different partitions, and the prediction node computes the changing rate of local topology to determine whether local status broadcast is needed. In or...

In Wireless Sensor Networks (WSNs), each sensor node can only use so much power before recharging. If energy is depleted too quickly, nodes will fail one by one, bringing down the network as a whole. To this end, design needed to reduce burden on nodes' supplies while extending network's useful life. This paper proposes new approach, called Energy Efficient Backup Node Assisted Routing, accompl...

An ad hoc wireless network supports data networking without an infrastructure, so that users can use network services while continually moving. Each move of the mobile host affects the topology of the network and the transmission route. The Ad Hoc Backup Node Setup Routing Protocol (ABRP) is proposed to focus attention on the intrinsic properties of the ad hoc wireless networks. Basically, ABRP...

In complex networks characterized by broad degree distribution, node significance is often associated with its degree or with centrality metrics which relate to its reachability and shortest paths passing through it. Such measures do not consider availability of efficient backup of the node and thus often fail to capture its contribution to the functionality and resilience of the network operat...

In an effort to combine research in peer-to-peer systems with techniques for incremental backup systems, we propose pStore: a secure distributed backup system based on an adaptive peer-to-peer network. pStore exploits unused personal hard drive space attached to the Internet to provide the distributed redundancy needed for reliable and effective data backup. Experiments on a 30 node network sho...

Mobile ad hoc networks (MANETs) have dynamic topology since all nodes have a random mobility behavior, which increases rerouting frequency and degrades communication performance. A more stable route can prolong route lifetime and reduce rerouting frequency. This paper proposes a Link lifetime based Backup Routing (LBR) protocol to improve route stability. LBR is based on link lifetime. It obtai...
