Mobile Backbone Wireless Networks (MBWN) [10] are wireless networks in which the base stations are mobile. Our strategy is the following: mobile nodes are dynamically grouped into clusters of bounded radius. In the very large wireless networks we deal with we deal with, several hundreds of clusters may be generated. Clustering makes use of a two dimensional Euclidean version of the Antipole Tre...

The development of mobile device technology, especially Android applications, is growing very significantly. focus this research how to build a mobile-based BTS (Base Transceiver Station) tower maintenance system. This system was built simplify and speed up the documentation reporting process for maintenance, thereby minimizing loss duplication files when performing maintenance. using Java prog...

In this paper, we consider the performance of a cellular radio direct-sequence code-division multiple access system. The base-to-mobile link is modeled as a flat Rayleigh fading channel, with all signals transmitted from a given base station fading in unison. For the mobile-to-base link, we use a similar model, except that the waveforms from all users are assumed to experience independent fadin...

An overview of research activity in the area of powering base station sites by means of renewable energy sources is given. It is shown that mobile network operators express significant interest for powering remote base stations using renewable energy sources. This is because a significant percentage of remote base station sites on the global level are still diesel powered due to lack of connect...

Most inherently distributed systems require self diagnosis and on-line monitoring. This is especially true in the domains of power transmission and mobile communication. Much effort has been expended in developing on-site monitoring systems for distributed power transformers and mobile communication base stations. In this paper, a new approach has been employed to implement the autonomous self ...
