A novel approach for prolonging the lifetime of a wireless sensor network using clustering routing protocol while maintaining desired quality of service attributes related to sensed data delivery is presented. This paper proposes a Multi-hop Cluster based Routing Protocol for long range transmission in wireless sensor network. The protocol consists of two parts, one is with respect to cluster management in sensor area and the other is about the data transmission between base station and the sensor area. The new clustering and routing algorithm's scale well and converge fast for large scale dynamic sensors as shown by our extensive results using the Network Simulator (NS2). It is a flexible tool for network engineers to vestigate how various protocols perform with different Configurations and topologies. Simulation results shows that the proposed protocol offers a better performance than single-hop clustering routing protocols in terms of network lifetime and energy consumption when the base station is located far away from the sensing area.Keywords

The next-generation mobile network will support terminal mobility, personal mobility, and service provider portability, making global roaming seamless. A location-independent personal telecommunication number (PTN) scheme is conducive to implementing such a global mobile system.
In this paper, firstly we propose multi tree database architecture consists of a number of database subsystems, each of which is a three-level t also proposes indexing schemes for each type of location databases and analyzes their efficiency and cost in terms of database access time and storage requirement. Tree structure and is connected to the others only through its ischolar_main. Results have revealed that the proposed database architecture for location management can effectively support the anticipated high user density in the future mobile networks.
