Wireless mobile ad hoc networks (MANETs) have the potential for use in important application environments, such as remote environmental monitoring, where energy resources are limited. Efficient power management is necessary to allow these networks to operate over a long period of time. One of the key factors affecting the design of power management mechanisms is the routing protocol in use with...

In this paper, we present an extensive ns-2.33 simulation based performance comparison of four widely known stability-oriented on-demand Mobile Adhoc Network (MANET) routing protocols. Our simulations show that modified Power DSR (PDSR) routes are more stable than existing DSR routes, which are more stable than DSDV and AODV routes. This also results in an increased packet delivery ratio for PD...

The specific features of mobile ad hoc networks (MANETs) impose new requirements for routing protocols. The aim of this paper is to present an approach that enhances routing performance by integrating ad hoc related characteristics. We propose a loop-free adaptive path energy conserving scheme which attempts to minimize both routing and storage overhead in order to efficiently provide robustnes...

Quality of Service (QoS) in Mobile Ad hoc Networks (MANETs) is a challenging task because of restricted resource and dynamic configuration. To support QoS, the link state information i.e. bandwidth, delay, cost, jitter, node energy and error rate in the network should be existed and manageable. The concentration of this paper is exploring the scope to QoS routing mechanism, to report the source...

Safety on roadways is expected to be achieved by using vehicular ad-hoc networks (VANETs). A VANET includes dynamically moving vehicles that communicate for a certain purpose. The routing procedure in the VANET protocol is required to deliver requested data packets to the vehicles in a short period of time. Conventionally, routing algorithms like the ad-hoc on-demand vector (AODV) routing, the ...

Mobile nodes of various routing protocols in Mobile Ad hoc Networks follow different strategies in transmission and receiving of data. Security, packet delivery and routing overhead are important concerns for any protocol during designing them. The presence and absence of malicious nodes in the network affect a lot on the performance of the protocol. This research is mainly focused on the study...

In recent years, many location based routing protocols have been developed for ad hoc networks. This paper presents the results of a detailed performance evaluation on two of these protocols: Location-Aided Routing (LAR) and Distance Routing Effect Algorithm for Mobility (DREAM). We compare the performance of these two protocols with the Dynamic Source Routing (DSR) protocol and a minimum stand...

Mobile Ad hoc network (MANETs) are rapidly growing as an important area of wireless communication with the technological advancements in the mobile devices. Efficient routing protocols make MANETs reliable. Despite the considerable simulation works, still more investigation is required in the performance evaluation of routing protocols for multimedia traffic especially Variable Bit Rate (VBR).I...

A Mobile Ad-hoc network (MANET) consists of a number of mobile wireless nodes, among which the communication is carried out without having any centralized control. 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 r...
