Mobile Area NETworks (MANETs) can be modelled as time-varying graphs their topology and traffic demands change. Optimizing routing in MANETs by proactively adapting the routes is a challenge, even with fixed user demand. Omniscient Dijkstra Routing (ODRb) one of best known approaches, which computes alternative paths but has limitations to mitigate congestions. In this paper, we investigate Gra...

(Under the direction of Dr. Wenye Wang). As various wireless networks evolves into the next generation to provide better services, a key technology, mobile ad hoc networks (MANETs), has emerged recently. The dynamic topology, multi-hop transmission, and the nature of wireless channels create many challenging research topics in the area of MANETs. Recently, there has been work on determining the...

This report addresses the problem of supporting multicast in mobile ad hoc networks (MANETs). Multicast is an important building block for many applications in MANETs, including data dissemination, service discovery, publish-subscribe, among others. It has been therefore widely studied and many solutions can be found in the literature. However, most solutions are tailored to a specific type of ...

Mobile ad hoc networks (MANETs) are of primary interest as new networks because of their flexibility. The Session Initiation Protocol (SIP) is the main signaling system in 3G and SIP servlets the main service provisioning framework. SIP is now being considered as a basis for signaling in MANETs. This makes the SIP servlets framework a chief candidate for service provisioning in MANETs. In this ...

 Abstract—Mobile ad hoc networks (MANETs) use has been well-known from the last few years in the many applications, like mission critical applications. In the (MANETS) prevention method is not adequate as the security concerned, so the detection method should be added to the security issues in (MANETs). The authentication and encryption is considered the first solution of the MANETs problem wh...

Common user applications cannot run in mobile ad-hoc networks (MANETs) before a method for name resolution is in place. While the Domain Name System (DNS) works well on the fixed Internet, it represents a centralized approach to name resolution, which is not suitable for MANETs. This article refines the framework developed for name resolution in MANETs and shows how a mechanism for local name r...

Mobile ad hoc networks (MANETs) are special kind of distributed networks that comprise wireless mobile nodes which can freely and dynamically self-organize into capricious and temporary manner. The demand for ubiquitous information access and spontaneous information exchange has multiplied considerably and with predictions to grow even more within the future. To satisfy this increasing demand, ...

Cooperative communication has been considered as a promising technique to improve communication quality of service (QoS) in wireless networks, including mobile ad hoc networks (MANETs). Due to their unorganized and decentralized infrastructure, cooperative MANETs (CO-MANETs) are vulnerable to attacks initiated on relays. Although encryption and authentication protocols may prevent compromised d...

The asymptotic throughput-delay tradeoff has been extensively studied for dense wireless mobile ad hoc networks (MANETs) as a function of increasing density. However, many practical applications exist for sparse MANETs where mobile node density goes to zero and the number of nodes is small. Asymptotic throughput-delay laws discovered for dense networks need not identically hold in this sparse r...

One of the important issue in MANETs is energy saving. Recent studies show that Network coding can reduces energy consumption by less transmission in MANETs. Encryption/decryption, transmission cost and transmission time are worked as source of energy consumption in MANETs. Network coding provides intrinsic security based on which encryption can be done quite efficiently, but to provide securit...
