This paper studies delay properties of the wellknown maximum weight scheduling algorithm in wireless ad hoc networks. We consider wireless networks with either onehop or multi-hop flows. Specifically, this paper shows that the maximum weight scheduling algorithm achieves order optimal delay for wireless ad hoc networks with single-hop traffic flows if the number of activated links in one typica...

Mobile ad hoc networks (MANETs) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self-organize into arbitrary and temporary, ‘‘ad-hoc’’ network topologies, allowing people and devices to seamlessly internetwork in areas with no pre-existing communication infrastructure, e.g., disaster recovery environments. Ad hoc networking concept is no...

Traditional ad hoc networks have flat architecture, which suffers from poor scalability. Theoretical analysis and experimental results imply that throughput for each node decreases rapidly toward zero while the number of nodes increases in such architecture. Hierarchical architecture in ad hoc networks present a trade off between cellular networks and pure ad hoc networks, in that data may be f...

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...

Hybrid ad hoc networks consist of two kinds of nodes, regular nodes and nodes with additional capabilities. For example, multi-hop cellular and wireless Internet networks consist of static or mobile nodes and access points to a fixed infrastructure. Each node may access fixed infrastructure either directly or via other nodes in multi-hop fashion. Another example is heterogeneous sensor networks...

A wireless multi-hop ad hoc network consists of a collection of nodes, which can communicate without any fixed base stations or networking infrastructure. Multi-hop ad hoc networks are ideally suited in areas such as sensor networking, community networking and networking used in emergency situations. Since transmission is wireless and nodes could be mobile, ad hoc networks bring about new chall...

Ad-Hoc wireless networks are self-organizing multi-hop wireless networks. Mobile ad hoc networks have some challenges like the design of an efficient routing protocol. The multipath routing protocol with load balancing provides a solution for the congestion network. Ad Hoc networks are setup as needed since they do not depend on the infrastructure. Ad Hoc networks are self–organizing multi hop ...

Wireless multi-hop networks have attracted the attention of the research community in the last years. Two classes of wireless multi-hop networks are usually considered: mobile multi-hop networks, usually referred to as ad-hoc networks, and fixed multi-hop networks, usually referred to as wireless mesh networks (WMN). WMN are a promising solution to provide both indoor and outdoor broadband wire...

Wireless mobile communications technology has been evolving rapidly in the past decade. The number of mobile subscribers has reached 2 billions and is expected to reach 3 billions by the end of 2010. Most countries have already deployed or have started to deploy the third generation (3G) wireless cellular networks. In 3G, in addition to traditional voice service, users are provided with multi-m...

This paper presents an analytical model based upon discrete time Markov chain analysis of receiver-initiated protocols for multi hop Ad hoc networks. Three-way receiver initiated (RTR-DATA-ACK) scheme for collision avoidance in Ad hoc networks has many protocols with it. In the proposed model, the nodes are randomly distributed according to a twodimension Poisson distribution with density λ. Fo...
