This paper proposes the solution for improving the services provided by the transport management by using GPS and GSM modem integration. The system mainly consists of three modules. (1) Bus station module (2) Bus module (3) Base station module. The modules are connected to PC and GSM modem. The initial information containing the bus number and license plate from bus station module is sent to bu...

Wireless Sensor Networks (WSNs) are consists of huge number of sensor nodes, restricted with limited power, for provide services with cooperation to sense data and send to server. Various routing techniques are introduced for managing data transmission in WSNs in last decade. This work proposes novel method with compare distance of sensor nodes to base station in heterogeneous WSN. The sensor n...

Abstract-Wireless Sensor Networks (WSNs) employ tiny sensor nodes to observe field and send data from the field to a Base Station. The base station is generally at a fixed location away from the observed field. However, such networks have limited life due to draining of batteries of nodes near the base station quickly in comparison to the nodes away from the base station. Further, data from nod...

This paper introduces a base station antenna system as a future cellular technology. The base station antenna system is the key to achieving high-speed data transmission. It is particularly important to improve the frequency reuse factor as one of the roles of a base station. Furthermore, in order to solve the interference problem due to the same frequency being used by the macro cell and the s...

Mobility has now a crucial requirement for wireless communication. Handoff is one of the major tasks that are used to support continuous transmission for a mobile terminal into different radio coverage area. In this paper, to enhance the wireless network capacity around tandem buses by setting up mobile base station and establishing several wireless interfaces along the roof of the tandem buses...

We address the problem of detecting a rogue base station (BS) in WiMax/802.16 wireless access networks. A rogue BS is a malicious station that impersonates a legitimate access point (AP). The rogue BS attack represents a major denial-of-service threat against wireless networks. Our approach is based on the observation that inconsistencies in the signal strength reports received by the mobile st...

In this paper computationally efficient signal shaping strategy is developed that can be used to substantially reduce the PAPR in multiband transmitters. In this report, we provide mathematical framework for design and analysis of PAPR reduction for multi-band transmitters. This paper addresses the problem of crest factor reduction ICFR) in multi-carrier WCDMA systems. A trade-off analysis for ...

Abstract With the proliferation of wireless standards such as GSM/EGPRS, WLAN, WiMAX, WCDMA, HSDPA/HSUPA, and WiBRO — future wireless radio base stations will need to support multiple air-interfaces, frequency bands and modulation formats. Radio technology that enables reconfigurable hardware across multiple standards is a big challenge for base station developers. In this paper base station ar...

Advances in wireless communication technologies have enabled the networking of devices, which conventionally operated standalone, to form an Internet of Things (IoT). A typical network architecture consists of a set of data sources that report to a base station (BS), e.g., a data aggregation unit, over multi-hop paths. An example of such a network operation model includes surveillance of an una...

during the planning of an UMTS radio network, there is a natural need for a base station positioning procedure. Good coverage at an acceptable level of network installation and maintaining costs, low interference and uniform interface load are the main requirements. In this paper we present an approach based on simulated annealing.
