An in-depth review of service discovery protocols (SDPs) in multihop mobile ad hoc networks analyzes SDP building blocks and determines SDP suitability based on architecture, mobility, and network size. Mobile ad hoc networks (manets) include a variety of devices, such as cell phones, PDAs, laptops, and other relatively larger devices. These devices can(More)
This paper is about energy efficient and robust implementation of random walks in mobile wireless networks. While random walk based algorithm are often proposed to solve many problems in wireless networks, their implementation is usually done at the application layer so that many characteristics of the wireless transmissions are not exploited. In this paper(More)
Mobile devices are inherently scarce in resources, necessitating the need to cooperate among them for performing tasks that cannot be done alone. This cooperation is in the form of services that are offered by other devices in the network. To get benefit from the services offered by other devices, they have to be discovered. Service Discovery Protocols(More)
It is a well-known fact that the partition is one of the main problems in p2p group membership. This problem rises when failures and dynamics of peer participation, or churn, occur in the overlay topology created by a group membership protocol connecting the group of peers. Solutions based on Gossip-based Group Membership (GGM) cope well with the failures(More)
Abstract: Service discovery in mobile ad hoc networks (MANETs) is a challenging issue. The nodes in a MANETs offer spontaneous and variable connectivity. Also the proximity of a given service as well as the kind and the number of services vary unpredictably with time. Traditional directory based architectural solutions can hardly cope with such a dynamic(More)
Cloud computing is based on virtualization, where a single physical resource is virtualized into multiple virtual resources. Processor and network virtualization offer many advantages like saving in hardware cost, energy consumption, human effort and management of resources. In this paper we have evaluated the effect of network and processor virtualization(More)
Since the performance of educational institutions depends critically on their students, it is imperative that educational institutions deploy an efficient and reliable admission criteria. In the context of Pakistan, a variety of admission criteria has been developed—mostly in isolation—by different universities. Despite the importance of these(More)
In this paper we propose an adaptive random walk for wireless networks. The lifetime of the walk is varied in such a way that at least a given fraction of nodes is covered, in expectation. The only parameter of the random walk, $\alpha$, depends on the nominal network size $N$ and on the required coverage. For sizes lower than $N$ the required coverage is(More)
