LOCATION BASED SPATIAL QUERY PROCESSING IN WIRELESS BROADCAST ENVIRONMENTS-MOBILE COMPUTING

Abstract: Location-based spatial queries (LBSQ s) refer to spatial queries whose answers rely on the location of the inquirer. Efficient processing of LBSQ s is of critical importance with the ever-increasing deployment and use of mobile technologies. We show that LBSQ s has certain unique characteristics that the traditional spatial query processing in centralized databases does not address. For example, a significant challenge is presented by wirel ....etc

Broadcast data delivery is used in most wireless systems to disseminate date items to all mobile elements inside a cell. This form of data delivery is different from the one in traditional client/server systems.

The data delivery in a traditional client/server system is pull-based: a client makes an explicit request to the server. The server receives the request, locates the information of interest and returns it to the client. And in most case point-to-point connection is employed - the communication channel between the server and a client ....etc

Multimedia Broadcast Multicast Service (MBMS)

This is a broadcasting service that can be offered via existing GSM and UMTS cellular networks and it also offers an option to use an uplink channel for interaction between the service and the user, which is not a common issue in the usual broadcast networks, like the conventional digital television which is only a one-way (unidirectional) system. MBMS uses multicast distribution in the core network instead of point-to-point links for each end device. ....etc

Direct broadcast satellite (DBS) also known as Direct-To-Home is a relatively recent development in the world of television distribution. ?Direct broadcast satellite? can either refer to the communications satellites themselves that deliver DBS service or the actual television service. DBS systems are commonly referred to as mini-dish systems. DBS uses the upper portion of the Ku band. Modified DBS systems can also run on C-band satellites and have been used by some networks in the past to get around legislation by some countries against re ....etc

Multimedia Broadcast Multicast Service (MBMS) is a broadcasting service that can be offered via existing GSM and UMTS cellular networks. The infrastructure offers an option to use an uplink channel for interaction between the service and the user, which is not a straightforward issue in usual broadcast networks, as for example conventional digital television is only a one-way (unidirectional) system. MBMS uses multicast distribution in the core network instead of point-to-point links for each end device .

Toward Broadcast Reliability in Mobile Ad Hoc Networks with Double Coverage. (A New TCP for Persistent Packet Reordering).

Abstract:

The broadcast operation, as a fundamental service in mobile ad hoc networks (MANETs), is prone to the broadcast storm problem if forwarding nodes are not carefully designated. The objective of reducing broadcast redundancy while still providing high delivery ratio under high transmission error rate is a major challenge in MANETs. In this paper, we propose a simple broadcast algorith ....etc

Multimedia broadcast multicast service (MBMS) is a standard developed by the third generation partnership project (3GPP) and is intended for distribution of multimedia content to mobile devices using broadcasting and multicasting Multimedia Broadcast and Multicast Services (MBMS) is a broadcasting service offered via existing GSM and UMTS cellular networks.It offers an option to use an uplink channel for interaction between the service and the user. MBMS uses multicast distribution in the core network instead . This system has the advantage ....etc
