Vehicular ad hoc network (VANET) technology has been identified as one of the key research area in these days. Improving road safety in VANETs requires efficient and reliable MAC protocols. These MAC protocols can be based on TDMA schemes. This paper, which presents an extensive overview of research related to Clustering-based Data Transmission for VANETs, shows how well these protocols can satisfy the stringent requirements of safety and user oriented applications.

As the explosion of wireless devices and services make the unlicensed spectrum increasingly crowded, traditional sensor networks operating on the unlicensed spectrum may suffer from severe interference caused by the nearby applications working on the same spectrum band. Cognitive radio sensor network (CRSN) has emerged as a promising solution to address the spectrum scarcity problem in traditional sensor networks, by enabling sensor nodes to opportunistically access licensed spectrum. In this paper we study various research papers on wireless sensor network to solve the problem of traditional sensor networks.

In the present paper, the authors explain certain expansion of the basic analogue of the I-function in relationship with the applications ofq-Leibnitz rule for the Weyl type q-derivatives of a product of two functions. Expansion formulae involving a basic analogue of H-function, Meijer’s G-function and MacRobert’s E-function have been derived as special cases of the results.

In the present paper, the authors derived the basic analogue of Mittag-Leffler function with the applications of q-beta function and obtain some important results of Mittag-Leffler function in terms of generalized wright function.
