Networks have become an integral part of all communications, associations, businesses, services, government/public organizations and human interactions around the globe. Emergence of technologies and dynamism of user needs & access pattern of network resources have shifted paradigm to wireless ad-hoc network infrastructure supporting mobile devices. Ad-hoc networking means building spontaneous ...

heretofore several position-based routing protocols have been developed for mobile ad hoc networks. many of these protocols assume that a location service is available which provides location information on the nodes in the network.our solutions decrease location update without loss of query success rate or throughput and even increase those.simulation results show that our methods are effectiv...

we study joint design of end-to-end congestion control and Per-link medium access control (MAC) in ad-hoc networks. In the current scenario wireless communication is emerging the world. Wireless Ad Hoc networks demands for higher intermediate node supports for long-range communication. Wireless Ad Hoc network is an emerging communication approach. Ad Hoc networks are usually defined as an auton...

Wireless ad hoc network is a special kind of wireless network with a dynamic topology consist of self organized nodes. The nodes in the networks are randomly and frequently. Due to the self organizing and decentralized capabilities, ad hoc networks are used for a wide range of civilian and military applications. Wireless ad hoc networks are an open environment and it is susceptible to many secu...

An ad hoc wireless network is a collection of wireless mobile nodes that self-configure to construct a network without the need for any established infrastructure or backbone. Ad hoc networks use mobile nodes to enable communication outside wireless transmission range. Due to the absence of any fixed infrastructure, it becomes difficult to make use of the existing routing techniques for network...

in recent years mobile networks have expanded dramatically, compared with other wireless networks. routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. in this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...

An ad-hoc wireless sensor network is also called self-organized networking that wireless sensor nodes can automatically communicate for each other. Therefore, each sensor node is no need for the information such as location of each sensor. Similarly, it consumes much energy on the information exchanged of each sensor node in order to maintain the entire ad-hoc wireless sensor network alive. The...

Many wireless networking problems have to be solved for the efficient design and deployment of these communications devices that operate in a Mobile Ad-hoc Network (MANET) environment. A Mobile Ad hoc Network (MANET) is an infrastructure less network of mobile devices which are equipped with a transmitter and receiver. If any node want to communicate with the other node then each node act as a ...
