We consider the geometric routing problem on mobile adhoc wireless networks such that we can send packets by only using local information at each node. We design a novel routing algorithm named directional routing algorithm by using random local neighbors such that the information can be efficiently maintained if each node dynamically changes its position. In our scheme, the number of hops and ...

due to limitations in computing resources of mobile nodes, mobile ad-hoc networks (manets) are very fault-prone. so far, redundancy at different levels of the network has been considered an efficient strategy to enhance the fault-tolerance of networks. indeed, ad-hoc networks are extremely redundant; therefore, natural redundancy to fault tolerance enhancement has a great impact on the network ...

Several research and development efforts have been made to ensure food security in developing countries. Dissemination of improved agricultural technologies was used as the main avenue through which some increases supply achieved. However, insecurity remains a major challenge. This paper argues provides empirical evidence that reducing loss waste can be an effective energy security, natural res...

Introduction: The ablation technique is one of the important therapeutic interventions for treatment of AV Nodal tachyarrhythmia. Different animal models have been developed to study the effects of ablation on the functional interanodal structure. The aim of the present study was to develop a new model of computer analysis to produce lesions by using direct voltage in isolated perfused rabbi...
