The main issues in Grid System are performance and Reliability. Achieving high performance Grid Computing requires techniques to efficiently and adaptively allocate tasks and applications to available resources in a large scale, highly heterogeneous, reliable and dynamic environment. Due to operational grid technology which expands the range and scale of(More)
The large computing capacity provided by grid systems is beneficial for solving complex problems by using many nodes of the grid at the same time. The usefulness of a grid system largely depends, among other factors, on the efficiency of the system regarding the allocation of jobs to grid resources. This paper proposes an Roulette Wheel Selection Genetic(More)
Zone Routing Protocol (ZRP) is a hybrid routing protocol used in ad-hoc networks. The authors have proposed a new routing protocol called, genetic zone routing protocol (GZRP) which is an extension of ZRP applied with genetic algorithms (GA) for finding the alternative routes in order to load balance the network and as well to resist to the link and/or node(More)
Computational grids have become attractive and promising platforms for solving large-scale high-performance applications of multi-institutional interest. However, the management of resources and computational tasks is a critical and complex undertaking as these resources and tasks are geographically distributed and a heterogeneous in nature.

In Mobile Ad-hoc Networks (MANETs) each node has a transmission radius and is able to send message to all of its neighbors that are located with in its radius. In reactive based routing algorithms such as Ad-hoc on demand Routing Algorithm (AODV) and Dynamic Source Routing Algorithm (DSR) a node broadcasts control information (Route Request, Route Reply,(More)
Wireless Mesh Networks (WMNs) has become an emerging technology in recent days due to its easy deployment and low setup cost. In WMN, Routing protocols play an important role and these are susceptible to various kinds of internal attacks. One such attack that has severe impact on a WMN is a wormhole attack. A Wormhole is a low-latency link between two parts(More)
