Mobile sensor network is the collection of independent and scattered sensors with capacity of mobility. In recent years, Mobility of Sensors has been utilized to improve the target coverage quality and network connectivity in randomly deployed mobile sensor networks. Target coverage and Network connectivity are two main challenging issues of mobile sensor networks. Target coverage covers a set ...

To obtain more accurate and comprehensive information from target monitoring area in mobile wireless sensor networks (mWSN), multiple area coverage is often considered. However, it may cause coverage holes and inefficiencies in a mWSN due to sensor nodes' moving, energy loss, physical damage, errors, failures or other factors. To address this problem, a k-coverage algorithm for mobile wireless ...

Currently, cellular networks are one of the essential communication methods for people. Providing proper coverage for the users and also offering high-quality services to them are two of the most important issues of concern in cellular networks. The fifth-generation cellular communication networks can provide higher data transmission rates, which lead to a higher quality of service but this hig...

Distributed systems consist of a number of network elements that interact with each other. As the number of network elements and interchangeable components for each network element increases, the trade off that the system tester faces is the thoroughness of test configuration coverage, versus limited resources of time and expense that are available. An approach to resolving this trade off is to...

In this paper, we apply the theory predicting neighbor distribution of arbitrary random graphs to analyze the network coverage of the peers in unstructured peer-to-peer(p2p) networks that use TTLbased flooding mechanism for search and query. However, we find that for many cases, the theory cannot be directly applied to obtain correct estimate of network coverage due to the presence of certain t...

Clustering for wireless sensor networks (WSNs) is an effective scheme in utilizing sensor nodes energy and extending the network lifetime, while coverage preservation is one of the most essential issues to guarantee the quality of service (QoS). However, the coverage problem has not been well understood so far. For mission-critical applications of networks, it is crucial to consider coverage re...
