Data dissemination is an essential task in large-scale wireless sensor networks (WSNs). While performing data dissemination under a battery power constraint, energy efficiency is a key design factor of routing protocol because deployed nodes cannot be replaced or recharged after deployment and a dead node may lead to the partition of whole networks. As a solution for the efficient data dissemination,...
An ad hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any established infrastructure or centralized administration. In such an environment, it may be necessary for one mobile host to enlist the aid of other hosts in forwarding a packet to its destination, due to the limited range of each mobile hostpsilas wireless transmissions. This paper presents...
A mobile ad hoc network (MANET) is a collection of mobile nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. In order to facilitate communication within the network, a routing protocol is used to discover routes between nodes. The primary goal of such an ad-hoc network routing protocol is correct...

Service discovery is a mechanism to find a specified service around service nodes (providers). In MANET, service discovery protocols should take mobility into consideration. Therefore, service discovery and MANET routing will cause significant overhead in terms of radio resource and battery life. In this paper, we propose a cross-layered service discovery protocol which considers both service discovery...
This work is concerned with defining a performanceindex that can be used as an objective measure in the evaluation and comparison of ad hoc networking protocols. Specifically, we introduce a performance index that aggregates performance results from multiple response metrics into a single scalar value that quantifies overall system performance, leading to more objective evaluations and comparisons...
