The paper presents an algorithm and simulation results for enhancing the communication network performance of a multiple mobile robot self-organizing Mobile Ad-hoc Network (MANET). The approach is based on the signal strength between the operator, an autonomous robot, and a remotely operated robot. The paper focuses on a new approach for autonomous robot control using signal intensity for robot motion...
Network Coding is a relatively new forwarding paradigm where intermediate nodes perform a store, code, and forward operation on incoming packets. Traditional forwarding approaches, which employed a store and forward operation, suffered from the limitations of the max-flow min-cut theorem wherein sources transmitting information over bottleneck links had to compete for access to these links. With Network...
Mobile ad-hoc networks (MANETs) are dynamic in nature. Links between nodes may constantly change due to mobility. The performance of the transmission control protocol (TCP) degrades in such an environment mainly due to its inability to differentiate between congestion and link failures which are frequent in MANETs. Several TCP variants were proposed to adapt TCP to a mobile environment. In addition,...
Topological changes in Mobile Ad-hoc NETwork (MANET) render routing paths unusable. Using multiple redundant paths between the source and the destination is a technique which reduces the affect of this problem. Shared links and nodes between paths present common failure points which can disable many or all of the paths. Disjoint path set requires the multiple paths to be link- or node-disjoint. However,...
In this paper, we present a modified on-demand routing algorithm for mobile ad-hoc networks (MANETs). The proposed algorithm is based on both the standard Ad-hoc On-demand Distance Vector (AODV) protocol and ant colony based optimization. The modified routing protocol is highly adaptive, efficient and scalable. The main goal in the design of the protocol was to reduce the routing overhead, response...
In this paper is presented a new model for intelligent traffic systems, which is able to integrate a typical surveillance scenario and topology independent immediate data delivery. Surveillance part is based on image analysis, namely general foreground/background modeling scheme. Data delivery system ensures data transmission over mobile Ad-hoc network, by providing communication framework for this...
In Mobile Ad-Hoc NETwork (MANET) there are many uncertainties like topological changes, number of nodes, mobility etc. Since the design of routing protocol is carried out by considering a particular environment, no existing routing protocol performs well for all possible environments and requirements. This paper proposes an adaptive protocol selector for MANET which helps in selecting an optimum routing...
We describe and verify convergence properties of our forced-based genetic algorithm (FGA) as a decentralized topology control mechanism distributed among software agents. FGA uses local information to guide autonomous mobile nodes over an unknown geographical terrain to obtain a uniform node distribution. Analyzing the convergence characteristics of FGA is difficult due to the stochastic nature of...
With the development of the multi-robot coordination, the working efficiency of the multi-robot system is improved, and the tasks can be finished better. Multi-robot coordination is one of the important issues for the research of mobile robot. The research of formation control of multi-robot will improve the efficiency of the coordination of multi-robot. So the problem of multi-robot formation is...
Ad-hoc wireless network is a collection of wireless mobile nodes forming a temporary network without any centralized administration. A typical paradigm of wireless networks, such as mobile ad hoc networks (MANETs), comprise a number of mobile nodes that can organize freely but need mutual cooperation for information exchanges. However, such networks also face several important challenges such as resource-limitation,...
In a mobile ad-hoc network (MANET), node mobility has a significant impact on the performance of routing protocols. Most of the previous research has been focused on entity mobility models, i.e., movements of the mobile nodes are independent of each other. In this paper, we investigate the impact of swarming behavior of mobile nodes, as observed in many mobile networks, on the performance of MANET...
In this paper, we present a solution of dynamic Ad-Hoc gateway to meet the urgent needs of interconnecting MANET to Internet. Comparing with the common fixed gateways, we integrate AODV with Mobile IP, eliminate the broadcast of Mobile IP by carrying the information in existing AODV messages so improve the performance remarkably. In this paper, we give the system's architecture design and its functional...

It is an auto-configuration inter-vehicle communication protocol, which supports ad-hoc and infrastructure networks, contains reactive and proactive routing...
The present work focuses on emulation and validation of protocol stacks for MANETs (mobile ad-hoc networks) that must support multimedia applications in a tactical environment. We considered a network consisting of some tens of mobile nodes, with randomly variable speeds in the order of some tens of km/h. Nodes are deployed on a scenario of a few km2 and have a radio range of some hundreds of meters...

The mobile ad-hoc network (MANET) is developing rapidly these years, but the dynamic nodes lead to unsteady topological structure. As P2P applications have advantages of performance, robustness, expansibility and so on, it is worth gathering the advantages of the MANET and P2P applications. This paper presents a design of messenger oriented P2P (MOP2P) framework in the MANET, and discusses its strong...
A mobile ad-hoc network (MANET) is a collection of mobile nodes which communicate over radio. These kinds of networks are very flexible, thus they do not require any existing infrastructure or central administration. Therefore, mobile ad-hoc networks are suitable for temporary communication links. The biggest challenge in this kind of networks is to find a path between the communication end points,...
The relative velocity between mobile devices is one of the key factors that determine the quality of communications in Mobile Ad-hoc NETworks (MANETs). Velocity estimates are useful in various aspects of ad hoc networking (e.g., predicting link lifetime and measuring performance). Conventional ways of estimating velocity rely on the availability of positioning systems such as the Global Positioning...
In this article, we have concentrated on selecting there liable path from source to destination in a mobile ad-hoc net work (MANET) framework using Dempster-Shafer Theory (DST) of evidence. The belief and plausibility functions are used here for calculating the suitable path for sending data packet from source to destination selecting the proper neighborhood on the basis of radio range of the source...
