It has been shown that in a mobile ad hoc wireless network per node throughput remains constant as the number of nodes approaches infinity, when the nodes lie in a disk of unit area. However, this requires that some packets are delivered indirectly by a relay node. In this paper, we prove, in the same setup, that D(k)2 (log k), where D(k) is the expected delay time of a mobile ad hoc wireless n...

Mobile ad hoc networks and wireless sensor networks have promised a wide variety of applications. However, they are often deployed in potentially adverse or even hostile environments. Therefore, they cannot be readily deployed without first addressing security challenges. Intrusion detection systems provide a necessary layer of indepth protection for wired networks. However, relatively little r...

Wireless ad hoc networks are growing important because of their mobility, versatility, and ability to work with fewer infrastructures. The mobile ad hoc network is an autonomous system consisting of mobile nodes connected with wireless links. Establishing a path between two nodes is a complex task in wireless networks. It is still more complex in the wireless mobile ad hoc network because every...

Now a day, security in Mobile Ad hoc Network (MANET) is very important issue. Due to dynamic topology and mobility of nodes, Mobile Ad hoc Networks are more vulnerable to security attacks than conventional wired and wireless network. Nodes of Mobile Ad hoc Network communicate directly without any central base station. That means in ad hoc network, infrastructure is not required for establishing...

An ad hoc network is a dynamically reconfigurable wireless network with no fixed infrastructure or central administration. Each host is mobile and must act as a router. Routing and multicasting protocols in ad hoc networks are faced with the challenge of delivering data to destinations through multihop routes in the presence of node movements and topology changes. This paper presents the On-Dem...

Abstract— Recent advances in wireless and micro electronic communications have enabled the development of a new type of wireless network called mobile ad hoc networks. MANETs are currently the greatest innovation in the field of telecommunications. A Mobile Ad hoc Wireless Network (MANET) is a collection of autonomous nodes that communicate with each other by forming a multi-hop network, mainta...

Abstract: Mobile ad hoc network is a collection of wireless mobile hosts which are interconnected by a communication media like radio. The communication network is formed without the aid of any centralized authority or preexisting infrastructure. By its characteristic this type of network is self-starting and self-organizing. It has been observed that mobile ad hoc networks can be exploited for...

Mobile ad hoc networks are dynamically organized by a collection of wireless mobile nodes. The mobile nodes in ad hoc networks can move arbitrarily thus the topology of network changes dynamically. Due to the properties of communication medium in wireless networks, unidirectional links may exist between mobile nodes thus results in the difficulty of link utilization and routing. In this paper, ...

Mobile Ad Hoc Network (MANET) is a kind of wireless ad hoc network. It is a self-managed network of mobile routers connected by wireless links with no access point. Every mobile device or node in a network is independently controlled in autonomous mode. The mobile devices are free to move randomly and organize themselves arbitrarily. The wireless ad-hoc network is particularly vulnerable due to...

These days MANET (Mobile Ad-hoc Network) is an amazing remarkably altering or rising technology, for the reason that of its elite nature of scattered mobile devices and self-motivated network topology. The mobile ad-hoc routing protocol follows several principles in wireless MANET’s. The up to date and novel applications based on wireless technology are being produced in the private as well as ...
