AODV is a prominent routing protocol for MANET that uses hop count as a path selection metric. However, AODV has no means to convey traffic load on current route. In this paper we propose a weight-based load balanced routing (WLBR) protocol for MANETs. The routing strategy projected in this paper focuses on distributing the traffic on the routes consisting of nodes with comparatively longer life and...

Finally, give a conclusion about our preliminary studies and this paper.
Modifying transmission control protocol (TCP) to improve its performance in wireless networks has been a long-standing research problem. Many methods have been proposed to improve TCPpsilas performance in mobile adhoc networks (MANETs). Among them ad hoc TCP (ADTCP) uses an end-to-end approach which requires minimal changes at the sender and receiver, provides the flexibility for backward compatibility,...
In existing clustering algorithms in mobile ad hoc networks, some of them consider only stability of cluster heads, and some others take only security into account, while only a few of them consider both factors. We propose Voting-based Clustering Algorithm with subjective trust and stability (VCA) by accessing subjective trust of node through Bayesian method and by evaluating stability of node through...
Mobile ad hoc networks (MANET), which comprise of mobile nodes connected wirelessly, are emerging as a very important technology for future generation of wireless mobile and ubiquitous computing. MANETs are being used in numerous application domains from emergency rescue and relief to wireless sensor networks. To support real-time communications (such as audio and video) over MANETs, new quality of...
In MANETs, the scalability problem has been solved by the clustering mechanism. However, current clustering algorithms consider on the network stability only in terms of some metrics affecting innercluster structure's stability, and neglect some metrics affecting intercluster structure's stability which are more favorable to global stability. To solve this problem, a clustering algorithm is proposed...
In the literature there are several location based routing schemes available for MANET. The effective management of location information has the maximum impact on the performance of this type of routing protocols. In this paper first we have made a study of the different categories of existing location services. Then we have proposed a new location management scheme which effectively implements the...
A Mobile Ad hoc NETwork (MANET) consists of a collection of mobile nodes. As MANETs are gaining popularity day-by-day, new developments in the area of real time and multimedia applications are rising as well. Such applications require Quality of Service (QoS) evolving in terms of the constraints such as bandwidth, end-to-end delay, jitter and energy. QoS provisioning for MANET can be achieved over...
The next generation communication systems will provide high quality multimedia services in a flexible and efficient manner. As an extension of next generation networks, Mobile Ad Hoc Networks (MANETs) have attracted significant attention amongst researchers. Nodes in a MANET have limited battery power. Hence, ad hoc routing protocols ought to be energy conservative to support real-time multimedia...
Due to lack of mass deployment of wireless ad hoc networks, simulation is the main tool to evaluate and compare different routing protocol proposals. Previous studies have shown that a certain routing protocol behaves differently under different presumed mobility patterns. Bypass-AODV is a new optimization of the AODV routing protocol for mobile ad-hoc networks. It is proposed as a local recovery...
In this contribution, we propose an original algorithm for self-localization in mobile ad-hoc networks. The proposed technique, based on interval analysis, is suited to the limited computational and memory resources of mobile nodes. The incertitude about the estimated position of each node is propagated in an interval form. The propagation is based on a state space model and formulated by a constraints...
This paper proposed a new score based clustering algorithm (SBCA) for mobile ad hoc networks (MANETs). MANETs are multi-hop wireless packet networks in which all the nodes cooperatively maintain network connectivity without the aid of any infrastructure networks. Through simulations we have compared the performance of the proposed algorithm with that of the WCA algorithm in terms of number of clusters,...
There has been great interest in service composition to exploit resources of distributed nodes in mobile ad hoc networks. During composite service execution, the execution path for composite service is very important because of its significant influence on network overhead and the percentage of failure. In this paper, we study the execution path selection problem, which focuses on selecting a short...
The task of finding and sustaining routes in mobile ad-hoc networks (MANETS) is an important factor in determining the efficiency of any MANET protocol. MANET characteristically comprises of wireless mobile hosts whose communication with each other is devoid of any fixed infrastructure. Absence of fixed infrastructures and host mobility thus constitute frequent unpredictable topological views. Positional...
In mobile ad hoc networks (MANETs), a source node must rely on other nodes to forward its packets on multi-hop routes to the destination. Therefore,the cooperation of nodes is very important. With lack of a prior trust relationship, misbehavior caused by selfishness or malice may severely degrade the performance of the network. The cooperative security schemes offer a reasonable effective solution...
A Mobile Ad-Hoc Network (MANET) is a decentralized network of autonomous mobile nodes able to communicate with each other over wireless links. Routing protocols for mobile ad-hoc networks has limitations such as frequent topology changes, limited battery power, bandwidth constraint, hidden and exposed node problem, high Bit Error Rate (BER) are major problems. Both proactive and reactive routing protocols...
The paper refers to the particular scenario where a set of naval units forms a WiMax-based mobile ad hoc network (MANET) to permit the communications among users on board of them and the sharing of the few satellite links towards the headquarter (HQ). In particular, the paper considers two different technical aspects: the definition of an appropriate architecture for the considered WiMax-based MANET...
IP traceback in MANET (mobile ad-hoc network) is more difficult than in traditional wired network because of the dynamically-changing topologies and limitation in resource. Researches in IP traceback for MANET largely follow the similar approaches as in the wired network and are having difficulties in overcoming the above mentioned topology and resource limitation problem. We suggest to cope with...

First, a MANET is comprised of logical grid hierarchy, and a streaming service...
With the proliferation of wireless devices, mobile ad-hoc networking (MANET) has become a very exciting and important technology. However, MANET is more vulnerable than wired networking. Existing security mechanisms designed for wired networks have to be redesigned in this new environment. In this paper, we discuss the problem of anomaly detection in MANET. The focus of our research is on techniques...
