Coverage in hybrid mobile sensor networks-IEEE TRANSACTIONS ON MOBILE COMPUTING, VOL. 7, NO. 11,8-glomosim


Abstract—This paper considers the coverage problem for hybrid networks which comprise both static and mobile sensors. The mobile sensors in our network only have limited mobility, i.e., they can move only once over a short distance. In random static sensor networks, sensor density should increase as O(logL+ k log logL) to provide k-coverage in a network with a size of L. As an alternative, an all-mobile network can provide k ....etc

Connected Sensor Cover: Self-Organization of Sensor Networks for Efficient Query Execution (Java)
IEEE/ACM Transactions on Networking, Vol. 14, No. 1

Abstract:
Spatial query execution is an essential functionality of a sensor network, where a query gathers sensor data within a specific geographic region. Redundancy within a sensor network can be exploited to reduce the communication cost incurred in execution of such queries. Any reduction in communication cost would result in an efficient use of the battery energy, which is ....etc

By combining an unstructured protocol with a DHT-based global index, hybrid peer-to-peer (P2P) improves search efficiency in terms of query recall and response time. The major challenge in hybrid search is how to estimate the number of peers that can answer a given query. Existing approaches assume that such a number can be directly obtained by computing item popularity. In this work, we show that such an assumption is not always valid, and previous designs cannot distinguish whether items related to a query are distributed in many peers or are ....etc

Exponential Synchronization of Hybrid Coupled
Networks With Delayed Coupling

Wangli He and Jinde Cao, Senior Member, IEEE


Abstract—

This paper investigates exponential synchronization
of coupled networks with hybrid coupling, which is composed of
constant coupling and discrete-delay coupling. There is only one
transmittal delay in the delayed coupling. The fact is that in the
signal transmission process, the time delay affects only the variable
that is being transmitted from one system to another, then it mak ....etc

A near-optimal multi cast scheme for mobile ad hoc networks using a hybrid genetic algorithm
Abstract: Multi cast routing is an effective way to communicate among multiple hosts in a network. It outperforms the basic broadcast strategy by sharing resources along general links, while sending information to a set of predefined multiple destinations concurrently. However, it is vulnerable to component failure in ad hoc network due to the lack of redundancy, multiple paths and multicast tree structure. Tree graph optimization problems (GO ....etc
