Mobile Ad Hoc Network (MANET) is collection of multi-hop wireless mobile nodes that communicate with each other without centralized control or established infrastructure. Nodes in MANETs are often collaborative for a particular task and have limited power. Congestion control and time delay is a key problem in mobile ad-hoc networks. In recent years, several routing protocols have been proposed ...

Ad-hoc networks are an emerging technology with immense potential. Recent advances in high-tech sensors, communication devices and microprocessors has given rise to a growing commercial interest in ad-hoc networks for inter-vehicular communications. Most of the research in inter-vehicular communication systems has focused on driver safety, accident reporting and multi-hop routing. There is an e...

Although MANET research has been ongoing for some time, there are relatively few experiences with real ad hoc networks. Instead, a large portion of protocol development is done in (often unrealistic) simulation settings only. In this paper we discuss lessons learned from our experimental work. Specifically, we present results for a fully functioning prototype implementing a p2p middleware (Free...

Efficient OSPF (Open Shortest Path First) operation on multi-hop ad hoc wireless networks has become desirable, as wireless community mesh networks and vehicular networks emerge using OLSR (Optimized Link State Routing), a link state MANET routing protocol similar to OSPF in many aspects. OSPF is already extensively deployed and well known in wired IP networks, and could provide simple, seamles...

Wireless ad hoc networks can be flexibly and quickly deployed for many applications such as automated battlefield, search and rescue, and disaster relief. Unlike wired networks or cellular networks, no physical backbone infrastructure is installed in wireless ad hoc networks. A communication session is achieved either through a single-hop radio transmission if the communication parties are clos...

Wireless sensor networks are very broadly used in many applications. Sensor networks still have problems in conveying data from one sensor node to other node. Routing algorithms are developed for wireless sensor networks. In this paper, some of them are discussed. These protocols still have some problems in sensor networks. Ad hoc networks and WSNs are similar to each other as both depend on ho...

Computer networks have long suffered from congestion. Congestion occurs when an increase in the offered load results in a decrease in the effective throughput of the network. The basic cause is that the short term packet arrival rate at some gateway exceeds its service rate. Existing congestion control schemes treat congestion as an individual problem and propose ad hoc solution that are dissat...
