Interconnection of multiple P2P networks has emerged as a viable solution to increase system reliability and fault-tolerance as well as to increase resource availability. In this paper we consider interconnection of large scale unstructured P2P networks by means of special nodes (called Synapses) that are co-located in more than one overlay. Synapses act as trait d’union by forwarding a query t...

Most critical sensor readings (Top-k Monitoring) in environment monitoring system are important to many wireless sensor applications. In such applications, sensor nodes transmit the data continuously for a specific time period to the storage nodes. It is responsible for transferring the received results to the Authority on Top-k Query request from them. Dummy data's were added into the original...

This paper examines the problem of incentivizing autonomous, self-interested nodes in an ad hoc network to cooperate in forwarding packets between non-adjacent nodes. We argue that assumptions about the homogeneity of nodes or their preferences are antithetical to the design philosophy of ad hoc networks. Instead, we postulate that a layered design consisting of policed but unpriced best-effort...

An adaptive, highly scalable, and robust web caching system is needed to effectively handle the exponential growth and extreme dynamic environment of the World Wide Web. Our work presented last year sketched out the basic design of such a system [31]. This sequel paper reports our progress over the past year. To assist caches making Web query forwarding decisions, we sketch out the basic design...

Wireless Sensor Networks require several sensing nodes in the network to transfer the sensed data to the base station so that it provides up-to-date information on the event. A routing protocol is often triggered in order to find a path to the sink so that the nodes can report the event to the sink. The principal task of a routing algorithm is to determine which set of intermediate nodes is to ...

This thesis addresses quality issues in Internet Protocol (IP) packet forwarding. In IP networks, queue mechanisms and scheduling can be used to construct multiple forwarding behaviors. Thereby, both relative and independent services can be offered to Internet users. Independent services offer forwarding qualities known beforehand. Users are assumed to explicitly request admission to an indepen...
