Mobile ad hoc networks (MANETs) have dynamic irregular topologies by nature, and suffer from inherent limitations such as limited bandwidth and power. A number of routing protocols have been proposed in the past few years to deal with these issues efficiently. The paper proposes and evaluates a new routing protocol, referred to here as the vector routing protocol (VRP). One of the main features...

A wireless mesh network (WMN) is a particular type of mobile ad hoc network (MANET), which aims to provide high bandwidth access for a large number of users. Shared nature of the wireless medium, static nodes and diversity of multiple paths between source and destination nodes makes designing of routing protocols makes a challenging task for wireless mesh networks when throughput, delay and pro...

QoS routing is the process of routing a connection based on the connection’s resource requirements. The overhead involved in QoS routing increases with the network size. State aggregation is an important technique that helps to reduce the overhead. In this paper, we propose a new state aggregation technique based on “network-flow”. Our approach allows a domain to update the aggregate sent by ot...

Experiments with wireless sensor networks have shown that unidirectional communication links are quite common. What is even more, they have also shown that the range of a unidirectional link can exceed that of a bidirectional one by far. Still, most of todays routing protocols do not use them, they only eliminate their implications. Those protocols that do use unidirectional links introduce a l...

We propose and analyze a new on the fly strategy that discovers, repairs and maintains routes in hierarchical and distributed fashion called Janitor Based Routing (JBR). The main motivation behind our JBR protocol is to decrease flooding and routing overhead and increase efficiencies in packet movement. An analytical model for the proposed JBR is presented and detailed simulation is used to obs...

mobile ad hoc networks (manet) are constructed by mobile nodes without access point. since manet has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. the olsr protocol is an optimization of the classical link state algorithm. olsr introduces an interesting concept, the multipoint r...

One critical issue of MANET is to improve packet delivery in presence of network dynamics. Proactive MANET routing protocols tend to provide smaller route discovery latency than ondemand protocols because they maintain route information to all the nodes in the network at all time. However, the downside for such protocols is the excessive routing control overhead generated by disseminating perio...

This paper presents a comprehensive survey of routing techniques in wireless sensor networks (WSN) and studies the advantages and performance issues of routing techniques with tradeoffs between energy and communication overhead savings. Based on the underlying network structure WSN routing algorithms can be categorized in flat, hierarchical, and location-based routing algorithms.

| Reducing forwarding state overhead of multicast routing protocols is an important issue towards a scalabile global multicast solution. In this paper, we propose a new approach, Dynamic Tunnel Multicast, which utilizes dynamically established tunnels on unbranched links of a multicast distribution tree to eliminate unnecessary multicast forwarding states. Analysis and simulation results show p...

Adhoc on demand distance vector routing protocol(AODV) is specially designed for mobile adhoc networks with reduced overhead using Expanding Ring Search technique. But energy consumption should also be considered in MANET due to battery constrain of the nodes. In this paper, we choose an energy efficient route discovery process for AODV based on Expanding Ring Search(ERS). We want to saves ener...
