In order to improve the control overhead and to achieve the reliable data transmission in the patient monitoring system based on ZigBee, here the concentration is given on the comparative performance evaluation of different routing algorithm in a wireless body area network (WBAN) using the OPNET simulation tools. WBAN contains the number of wireless mobile nodes forming an unpredictable topolog...

Mobile ad-hoc networks (MANET) is a network mode that does not depend on infrastructure and central access. The fast flexible networking of MANET renders its wide applications in specific scenarios. However, rapidly changing topology open channels bring potential security problems. In this paper, we proposed an active-routing authentication scheme (AAS) based the characteristics active routing ...

Abstract. In this paper, we present Chapar, an event system designed for mobile ad hoc networks that supports the publish-subscribe model as well as pointto-point and point-to-multipoint message sending. Chapar supports event persistency to resist transient disconnections and network partitioning. Following a cross-layer approach, Chapar is designed as an overlay network that uses the Multipoin...

The main ad hoc routing protocols that were proposed generally provide only flat networks. However the Internet has always been of a hierarchical nature, for scalability and manageability reasons. This paper therefore introduces a simple mechanism providing dynamic clustering with OLSR, one of the MANET routing solutions, chosen for its ease of integration in the Internet infrastructure. This c...

One of the main challenges for mobile ad hoc networks is to design routing protocols that cope efficiently with dynamic network topologies. In this paper, we propose a new routing protocol called Multi-Path Optimized Link State Routing Protocol (MP-OLSR). The main idea is to use the sizeable amount of information collected by every node in OLSR in order to select not one but several reliable ro...

This document describes the Optimized Link State Routing (OLSR) protocol for mobile ad hoc networks. The protocol is an optimization of the classical link state algorithm tailored to the requirements of a mobile wireless LAN. The key concept used in the protocol is that of multipoint relays (MPRs). MPRs are selected nodes which forward broadcast messages during the ooding process. This techniqu...

In this paper focus on Nature of-administration (QoS) steering in an Ad-Hoc system is troublesome on the grounds that the system topology may change always and the accessible state data for directing is innately uncertain. In the proposal, we create QoS forms of the OLSR (Optimized Link State Routing) convention, which is an "expert dynamic" Ad-Hoc directing convention. We acquaint heuristics t...

The aim of this research is to evaluate the performance of OLSR using swarm intelligence and HPSO with Gravitational search algorithm to lower the jitter time, data drop and end to end delay and improve the network throughput. Simulation was carried out for multimedia traffic and video streamed network traffic using OPNET Simulator. Routing is exchanging of information from one host to another ...

The performance of mobile ad-hoc networks (MANET) is related to the efficiency of the routing protocols in adapting to frequently changing network topology and link status. This paper addresses the issue by comparing the relative performance of three key ad-hoc routing protocols: Destination-sequenced Distance Vector (DSDV), Ad-hoc Ondemand Distance Vector (AODV) and Optimized Link State Routin...

Mobile ad hoc networks (MANETs) are proposed for emergency situations because they are self-organized and infrastructure-less. However, the mobility of the nodes and the lack of infrastructure pose challenges to the routing protocols. The signaling of these protocols is affected by the same problems as the data traffic: a multi-hop environment with limited bandwidth, collisions and bit errors. ...
