Almost all proposed routing protocols are based on minimum hops in mobile ad hoc network. But through the research on the real communication of wireless nodes, we find that sometimes the path which has the minimum hops from the source to the destination may not be the best path. Considered the remaining power and the node selfishness, we propose an improved AODV routing protocol, I-AODV in this paper...
Ad hoc networks (MANET) frequently changing network topology using multi-hop wireless links without existing network infrastructure. Anycast routing is important for Ad hoc network in terms of resource, robustness and efficiency when mobility is high and links get disconnected frequently. Performance of two anycast based reactive routing protocols for mobile Ad hoc networks-Anycast Routing based Dynamic...
Energy saving and traffic load balancing are two important issues that affect the performance of wireless networks, especially MANET. In this work, a novel routing algorithm over MANETs called LBE-ARAMA has been proposed. It allows to discover minimum MDR paths preserving the energy and to balance the data traffic through the round trip time (RTT) delay evaluation on the path from source to destination...
In this paper, we attempt to elongate the network lifetime by balancing energy usage, namely, allocating packets via multiple paths proportionally to the energy metric of each path. We propose the static and dynamic strategies of collecting energy metric values and allocating packets, and apply them to AOMDV. Performance comparisons of the proposed methods and original AOMDV are carried out in simulation...
Non-real-time communication is the markedness of vehicular ad hoc networks (VANETs) because of the rapidly changing topology. A delay/disruption tolerant network (DTN) is defined as a dynamic network where the contacts among participants of the network are intermittent or link performances are highly unsteady. In such a periodic and disrupted network, message ferry (MF) is designed to collect and...
Low resource availability in Mobile Ad hoc NETworks (MANETs) requires efficient utilization of resources and imposes severe demands on routing protocols, motivating their study, since the existing (for wired networks) routing protocols perform poorly, due to the unique characteristics of MANETs. The Dynamic Source Routing (DSR) protocol is one of the most important, simple, and efficient reactive...
Mobile Ad Hoc networks (MANET) are created temporarily for the purpose of either communication, sharing services and resources or running applications such as multi-player game. As sharing assumes discovery and routing, we propose a new service that integrates these two services in a cost-effective manner. The limited life time of MANET requires effectiveness in terms of how resources such as battery...
This paper presents a hybrid routing protocol based on Mobile Agent (HRPMA) for Ad Hoc Networks (MANET). In the proposed approach, a few mobile agents move in the network and communicate with each node. They collect the network information to build the global information matrix of nodes. The data packets are transferred according to the matrix by a routing search algorithm. We have done the experiments...
Current approaches for service discovery in Mobile ad-hoc Networks (MANETs) are optimized for highly dynamic environments. These approaches do not scale in Wireless Mesh Networks (WMNs) which are intended for long-time usage. Service discovery approaches for static wired networks are also not applicable. We present a scalable two-layered approach for service discovery in WMNs where clients communicate...
In this paper, we efficiently adapt the prominent Ad Hoc On-Demand Distance Vector (AODV) routing protocol with a reactive Local Link Repair, AODV-LR, for effective deployment in restricted power-budget and bandwidth mobile ad hoc sensor networks (MASNET). We introduce a better replacement mechanism to the local repair phase of the AODV. Our new approach is a preemptive, self-repairing AODV (called...
Mobile ad hoc networks are a class of dynamic networks without any centralized administration. A major bottleneck in mobile ad hoc networks (MANETs) is the energy consumption since nodes are usually mobile and battery operated. To maximize the lifetime of mobile ad hoc networks (i.e., the lifetime of the nodes themselves) the power depletion of network must be evenly distributed, i.e., there must...
This study elaborates the influence patterns of different backup strategies on AODV-based routing protocols. Although some backup routing strategies yield good data delivery rates, they suffer from low efficiency. To make the process of data salvation more efficiently in case of link failure, we explore the possibility of combining the AODV-BR strategy and on-demand node-disjoint multi-path routing...
Dynamic and efficient routing is one of the key challenges in wireless ad hoc networks. In this paper, based on a reactive AODV protocol, a novel semi-proactive routing protocol, named SP-AODV, is presented that uses proactive routing for some special nodes. The efficiency of the new protocol lies in the fact that some nodes with certain conditions will dynamically update some sections of their routing...
Multimedia data communication in mobile ad hoc networks involves link un-stability and link-failures. So the existing design of routing protocols failed to achieve a stable QOS. In this paper, we developed an ant colony-based routing protocol for multimedia communications in mobile ad hoc networks. The routing protocol first establishes multiple paths between the source and destination of a data session...
Mobile ad hoc networks faces great challenge in group key establishment dues to its characteristics such as mobility, unreliable links, and multi-hop communications delay. In this paper, SODMRP (secure on-demand multicast route protocol) is proposed based on ODMRP (on-demand multicast route protocol) and Identity-Based cryptography, which secures the multicast routing ,and establishes group key during...
This paper reports the studies related to scalability of network size on our newly proposed routing protocol, genetic zone routing protocol (GZRP) for mobile ad hoc networks (MANETs). This protocol applies genetic algorithms (GA) to zone routing protocol (ZRP) for finding a limited set of multiple alternative routes to the destinations, in order to provide load balancing and fault tolerance during...
Wearable computers need networking by using wireless ad hoc network in order to utilize them more effectively, routing protocol becomes an important research field for its significance in wireless ad hoc network. In Ad Hoc network, there are mainly two kinds of routing protocols: proactive routing protocol and on-demand routing protocol, to evaluate the performance of two kinds of protocols, we choose...
The performance of routing protocols in mobile ad hoc network (MANET) always attracts many attentions. As many previous works have shown, routing performance is greatly dependent to the availability and stability of wireless links. Although there are some studies reported to evaluate the performance of routing protocols in MANET, little work is done for the system overall performance, which is generally...
A multimetric QoS routing protocol (MQOLSR) is proposed in this paper, which providing different QoS for different applications flow in an ad hoc network. The protocol, which integrates QoS measurement and packet forwarding, expands the topology discovery and routing computing mechanism of the OLSR protocol. It can provide different routing and forwarding service according to different application...
Ad hoc wireless networks are decentralized in nature and hence routing is a central challenge in this type of network. In this paper we describe a simulation model to simulate the routing protocols for wireless ad hoc networks and analyze the results from the simulation for performance evaluation. The simulation model incorporates the number of parameter values with changing environmental factors...
