In sparse mobile sensor networks, nodes have a small number of neighbors with intermittent connectivity. This paper presents a new networking protocol for this type of network, aimed at maximizing system performance in terms of both delay and reliability. The system is motivated by the observation that many applications on this type of network have two kinds of co-existing data packets: those with...
Sensor networks are composed of many sensors usually far from the region is available. Routing in wireless sensor networks for the transfer of information from sensor nodes to base station is especially important. Optimum consumption of energy is important requirements in wireless sensor networks because sensor systems typically use battery power. In this paper with a routing algorithm to determine...
Multimedia communication networks, such as the Internet, are heterogeneous in their nature due to the usage of different methods for content distribution. The efficiency of multimedia distribution depends on the variety of communication protocols that are simultaneously running (composed) over different network hosts in order to resolve packet conflicts. A very natural question that arises in such...
Overlay networks have emerged as a means to enhance end-to-end application performance and availability. Network topology plays an important role in utilizing resources in peer-to-peer systems. Epidemic algorithms are potentially effective solutions for disseminating information in large scale and dynamic systems. P2P networks are popular for their dynamicity, but they are easy to deploy, robust and...
A Mobile Ad hoc Network (MANET) is a transitory, dynamic, decentralised, self-organised and infrastructure-less network. This unique nature introduced new challenges in the security research field such that it became imperative to design new security mechanisms that suit these characteristics. The proposed work contributes to the problem of securing data forwarding in the network layer; this is accomplished...
