Mobile ad hoc networking is a challenging task due to the lack of resources in the network as well as the frequent changes in network topology. Although lots of research has been done on supporting QoS in the Internet and other networks, but they are not suitable for mobile Ad hoc networks and still QoS support for such networks remains an open problem.

Mobile Adhoc Network (MANET) is characterized by mobile hosts, dynamic topology, multi-hop wireless connectivity and infrastructureless ad hoc environment. The adhoc environment is accessible to both legitimate network users and malicious attackers. Moreover, as the wireless links are highly error prone and can go down frequently due to mobility of nodes,(More)
A recent trend in ad hoc network routing is the reactive on-demand philosophy where routes are established only when required. Most of the protocols in this category, however, use single route and do not utilize multiple alternate paths. This paper proposes an analytical analysis of energy parameters, their usage and their evaluation in ad hoc networks. The(More)
A Mobile Adhoc Network (MANET) is characterized by mobile nodes, multihop wireless connectivity, Non infrastructural environment and dynamic topology. In Ad Hoc network routing is the reactive on-demand philosophy where routes are established only when required. Stable Routing, Security and Power efficiency are the major concerns in this field. The ad hoc(More)
A “Mobile Ad hoc Network” is an autonomous system of mobile hosts which are free to move around randomly and organize themselves arbitrarily. 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 and efficient route(More)
MANET is a self organized, self configurable network having no infrastructure, and in which the mobile nodes move arbitrarily. The mobile nodes can receive and relay packets as a router. Routing is a critical issue and an efficient routing protocol makes the MANET reliable. The provision of quality of service (QoS) guarantees is much more challenging mainly(More)
A recent trend in Ad Hoc network routing is the reactive on-demand philosophy where routes are established only when required. Most of the protocols in this category are not incorporating proper security features. The ad hoc environment is accessible to both legitimate network users and malicious attackers. It has been observed that different protocols need(More)
