Wireless communication encapsulates the earth into a global village with its reach to every nook and corner of the globe. The fourth generation (4G systems) of wireless communication was expected to be up for grabs from 2010s. However, due to the complicated hardware required the evolution of technology into 4G has been sluggish. Since 4G services require(More)
Mobile Ad-hoc Networks (MANETS) is a collection of wireless nodes without any infrastructure support. The nodes in MANET can act as either router or source and the control of the network is distributed among nodes. The nodes in MANETS are highly mobile and it maintains dynamic interconnection between those mobile nodes. MANTEs have been considered as(More)
Mobile Ad-hoc Network (MANET) is an emerging research area as it utilizes a diversity of applications. MANET is a self configuring network with dynamic topology. The network does not have any permanent infrastructure and the network can be formed on the fly. The mobile nodes in the network move frequently and the topology changes dynamically. So there is a(More)
Mobile Ad hoc network termed as MANET is a collection of wireless mobile nodes, which dynamically form a temporary network without any existing network infrastructure. Cluster based routing includes role based routing such as cluster head performs observer role, one of the cluster member act as source/sink role. Cluster based routing includes both reactive(More)
Vehicular adhoc network (VANET) is formed by vehicles that move in well-defined paths and it is highly dynamic. The routing in VANET by relying beacons suffers from significant drawbacks such as temporal loops in forwarding path, consumes available bandwidth, backward progress due to stale information etc. So here proposes an enhanced secured routing(More)
4G communication systems provide a global communication standard for each and every communication facilities and internet and telecommunication service providers of the globe. The major attraction of 4G is the network selection policy which enables users to select services offered by the best of the various service providers. The main purpose of this paper(More)
In Wireless Sensor Network, the communication generally takes higher energy than other operations like sensing and data processing. So the traffic reduction in communication is one of the most important concern for prolong the life of sensors. This paper presents three traffic reduction techniques based on dominating set. In the first approach base station(More)
Mobile Ad-hoc Networks (MANETS) consists of a collection of mobile nodes without having a central coordination. In MANET, node mobility and dynamic topology play an important role in the performance. MANET provide a solution for network connection at anywhere and at any time. The major features of MANET are quick set up, self organization and self(More)
MANET (Mobile Ad Hoc Network) consists of mobile nodes having no fixed infrastructure. These networks have dynamic topology and all the nodes are in general autonomous. Normally network comprises of selfish individuals that are not willing to forward the packets but wants to forward their own messages. In ad hoc network throughput increases when all(More)
