The number of contending neighbors of a node in a multihop ad hoc network has to be adjusted while analyzing the performance of the network such as computing the end-to-end delays along a path from a given source to a destination. In this paper, we describe a method to adjust the number of contending neighbors of a node in a multihop wireless ad hoc network. Our method is based on the minimum n...

Due to the fact that high datarate has shorter transmission range, the benefit of using high datarate may be degraded for IEEE 802.11 based multihop ad hoc networks. In this paper, we evaluate the performance of multihop ad hoc networks at multirates, in terms of the number of hops between source and destination, throughput, and end-to-end delay. Through simulations carried out in chain topolog...

Broadcast protocols play a vital role in building services and applications for multihop, mobile, wireless ad hoc networks (MANET). This paper describes the design, implementation and evaluation of a new broadcast protocol for a multihop, mobile wireless ad hoc network that provides significantly better performance than the currently existing protocols. In particular, this protocol provides low...

Providing service discovery in an efficient and scalable way in ad hoc networks is a challenging problem, in particular for multihop scenarios, due to the large number of potential participant nodes and the scarce resources in these networks. In this paper, we propose and evaluate an approach to mitigate the reply implosion problem in querybased service discovery protocols for multihop mobile a...

Multiple wireless terminals jointly create and maintain ad hoc networks without the help of central entities. Possible applications for such networks are in urban areas to avoid additional costs for communicating over cellular networks. Whenever two nodes are not within each others proximity, they use multihop connections for data exchanges. Ad hoc routing algorithms are utilized to setup these...

Multihop ad hoc networks were designed assuming trustworthiness and cooperation between all participating nodes; nodes in an ad-hoc network rely on one another in packet forwarding, detecting routes, etc. Thus, the performance of an ad hoc network degrades considerably with the presence of misbehaving nodes. Nodes’ misbehaviour includes, but is not limited to, refusing to relay data packets, co...

Multihop ad-hoc networks have a dynamic topology. Retrieving a route towards a remote peer requires the execution of a recipient lookup, which can publicly reveal sensitive information about him. Within this context, we propose an efficient, practical and scalable solution to guarantee the anonymity of recipients’ nodes in ad-hoc networks. key words: anonymity, cryptography, scalability, ad-hoc...

The utilization of Internet Things (IoT) technology, especially in remote areas, is still relatively low, even though the technology required to implement smart farming or villages, which aims improve quality life people rural areas. high investment cost for IoT networks that use cellular Wi-Fi one causes slow implementation this technology. Our previous research has developed an alternative ne...
