    Genetic Zone Routing Protocol

    In multi-hop wireless networks such as ad hoc networks, mobile users need to communicate where there is no fixed networking infrastructure or no time to create such an infrastructure. The idea of ad hoc networking is sometimes also called infrastructure-less networking. Mobile Ad hoc NETworks (MANETs) are created dynamically. The...

    Review and Implications of Time Division Multiple Access Techniques for Wireless Environment Services and Applications

    Time Division Multiple Access (TDMA) is a channel access method for shared medium (usually radio) networks. It allows several users to share the same frequency channel by dividing the signal into different timeslots. The users transmit in rapid succession, one after the other, each using his own timeslot. This allows...

    Deriving Cluster Knowledge Using Rough Set Theory

    Clustering algorithms gives general description of the clusters listing, number of clusters, and member entities in those clusters. It lacks in generating cluster description in the form of pattern. Deriving pattern from clusters along with grouping of data into clusters is important from data mining perspective. In the proposed approach...
