Handover is a critical issue for wireless networks of various protocols including IEEE 802.16e. In this paper we propose an efficient handover scheme which reduces the number of packets required to be transmitted for handover and increases the channel availability. It is based on a concept of group-based channel scan and scheduled handover with the mobile stations (MSs). Computer simulation reveals...
Mobility management in wireless environment is important to support real-time services with increasing usage of wireless internet. The packets based on Internet Protocol (IP) are classified by edge router depending on the traffic conditioning agreement (TCA) in the differentiated services (DiffServ) domain. The core routers then forward the packets differently depending on the PHB (Per Hop-Behavior)...
Nowadays, handover is a critical issue for real-time applications in wireless networks. In this paper we propose more efficient handover solution with reducing the number of handover packet for the mobile station (MS) in handover process to scan. It is based on a concept of BSs channel information with a group-based scan technique. The base stations (BSs) choose the number of channel and indicate...
As the rate of sexual crimes soars, new law mandates the sex offenders to wear an electronic anklet identifying their location. Here a middleware is needed to monitor and manage wide area of a number of entities. The existing middleware is somewhat inefficient in covering such vast area of specific application. This paper proposes a context-awareness middleware structure which monitors the distance...
