Wireless ad-hoc network is a resource constrained network applied in many applications. Clustering is considered to be most competent technique in order to attain firm performance and improved utilization of energy. Traditional clustering tactics elect a cluster coordinator commonly known as cluster heads so as to manage the whole cluster in terms of data collection, data fusion and transmission of...
The routing protocol is able to improve the performance of the network as compared to the traditional 3G and WiFi offload. On this study, the concept Genetic Zone Routing Protocol (GZRP) will be combined with the VHO algortihm used at the multiple base stations in 3G-WiFi offload network. Based on the results of this simulation the proposed algorithm can improve troughput and reduce handover delay...
A Mobile Ad hoc Network (MANET) is a collection of two or more mobile devices (PDA, laptop, cellphones, etc.) it is getting more and more important for mobile users to discover resources (eg: Printer, fax machines) without any need of configuration. To this end service discovery is an important feature of MANET. In this paper we propose a novel architecture that the cluster based service Discovery,...
Ad hoc relaying schemes are introduced as an effective mechanism for load balancing in wireless cellular systems. The relays facilitate channel sharing between the adjacent sectors of the neighboring cells, for the calls that are originated within their coverage area. In this paper, two configurations for relay deployment in sectorized cellular systems are presented. In each case, the probability...
A mobile ad hoc network (MANET) consists of a set of mobile hosts that can communicate with each other without the assistance of base stations. The multipath routing in mobile ad hoc networks is difficult because the network topology may change constantly, and the available alternative path is inherently unreliable. Multi-path routing represents a promising routing method for wireless mobile ad hoc...
In a cellular network, if there are too many data users in a cell, data may suffer long delay, and system's quality-of-service (QoS) will degrade. Some traditional schemes such as dynamic channel-allocation scheme (DCA) will assign more channels to hot (or overloaded) cells through a central control system (CC) and the throughput increase will be upper bounded by the number of new channels assigned...
