OLSR is a recent routing protocol for multi-hop wireless ad-hoc networks standardized by the IETF. It uses the concept of Multi-Point Relays (MPR) to minimize the overhead of routing messages and limit the harmful effects of broadcast in such networks. In this report, we are interested in the performance evaluation of Multi-Point Relays selection. We analyze the mean number of selected MPR in t...

Incorporating multi-hop wireless networks in the IP infrastructure is an effort to which a growing community participates. One instance of such activity is the extension of the routing protocol OSPF, for operation on MANETs. Such extension allows OSPF, the most widely deployed interior gateway routing protocol on the Internet, to work on heterogeneous networks encompassing both wired and wirele...

Ad-hoc networks are a key in the evolution of wireless networks. Ad-hoc networks are typically composed of equal nodes, which communicate over wireless links without any central control. Ad-hoc wireless networks inherit the traditional problems of wireless and mobile communications, such as bandwidth optimisation, power control and transmission quality enhancement. In addition, the multi-hop na...

Previous analysis of collision avoidance in ad hoc networks with hidden terminals has focused on senderinitiated schemes, like the IEEE 802.11 distributed coordination function. This paper presents analytical modeling of receiver-initiated collision avoidance schemes in multi-hop ad hoc networks. Our analysis shows that receiver-initiated schemes can offer substantial improvements over senderin...

Most peer-to-peer file storage sharing systems work on wired networks. Due to the multi-hop wireless communication nature in ad-hoc networks, the development of mobile ad-hoc network file storage sharing system faces many challenges. In this paper, a hypothetical partitionable mobile file system (PMFS) is proposed. This new PMFS is a distributed file storing/sharing system built on partitionabl...

The number of hops between the source and destination nodes is a key parameter in studying multi-hop ad hoc networks analytically. To the best of our known, there is no analytical work that considers the hop count of paths in MANETs in a random mobility environment. This paper presents a theoretical study for the expected number of hops between any random source-destination pair in multi-hop ad...

The paper focuses on two emerging technologies for constructing a Mobile ad hoc network: IEEE 802.11 and Bluetooth. The IEEE 802.11 standard is a good platform to implement a single-hop ad hoc network because of its extreme simplicity. Furthermore, multi-hop networks covering areas of several square kilometers could be built by exploiting the IEEE 802.11 technology. On smaller scales, technolog...

Wireless multi-hop ad hoc communication networks represent an infrastructure-less and self-organized generalization of todays wireless cellular networks. Connectivity within such a network is an important issue. Continuum percolation and technologydriven mutations thereof allow to address this issue in the static limit and to construct a simple distributed protocol, guaranteeing strong connecti...
