Wireless Sensor Network (WSN) has become one of the current technologies in the world of information technology. Coverage and connectivity are the main requirement that reflects the performance and quality of services in WSN applications. In WSN applications with a large scale area, the sensor nodes are deployed randomly in a noninvasive way. The deployment process will cause some issues such a...

Increasing the productivity of simulation-based semiconductor design verification is one of the urgent challenges identified in the International Technology Roadmap for Semiconductors. The most difficult aspect is the generation of stimulus for functional coverage closure. This paper introduces a new CoverageDirected test Generation (CDG) feedback loop which applies Inductive Logic Programming ...

Efficient network coverage and connectivity are the requisites for most Wireless Sensor Network deployments, particularly those concerned with area monitoring. The Coverage Control Technology is one of the basic technologies of wireless sensor network, and is mainly concerned about how to prolong the network lifetime on the basis of meeting users’ perception demand. To optimize wireless sensor ...

Narrowband Internet of Things (NB-IoT) is a new cellular technology introduced in 3GPP Release 13 for providing wide-area coverage for the Internet of Things (IoT). This article provides an overview of the air interface of NB-IoT. It describes how NB-IoT addresses key IoT requirements such as deployment flexibility, low device complexity, long battery life time, support of massive number of dev...

the global investigation of disasters in recent years shows that their number has increased annually and the number of affected people and costs of disasters are increasing

Automating the generation of object-oriented unit tests for structural testing techniques has been challenging many researchers due to the benefits it promises in terms of cost saving and test quality improvement. It requires test sequences to be generated, each of which models a particular scenario in which the class under test is examined. The generation process aims at obtaining a preferably...
