Wireless radio relays are one of the possible contenders to extend the capacity and reliability of broadband data channels envisaged for 4G and above. Several research and standardization groups are engaged in evaluating and evolving the range of applications with radio relays. There are both pros and cons of this technology, which needs to be carefully addressed before its actual implementation....
Wireless sensor networks (WSNs) is composed of sink and many sensor nodes. It has the great scope to monitor environment and the characteristics of wireless communications. Relatively, the advantages of sensor node bring themselves some restrictions. The greatest challenge among those is the constraints on energy. The most critical issue is how to minimize the energy consumption for keeping target...
Real-time patient monitoring is critical to early detection of clinical patient deterioration in general hospital wards. A key challenge in such applications is to reliably deliver sensor data from mobile patients. We present an empirical analysis on the reliability of data collection from wireless pulse oximeters attached to users. We observe that most packet loss occur from mobile users to their...
This paper describes how we can use existing mobile technology to track the vehicle. Here the embedded system along with the mobile is used to prevent the vehicle from being stolen and also if the vehicle is stolen then its location can be tracked. Mobile technology is the fastest growing communication mode. In todaypsilas mobile technology we all are acquainted with short message service (SMS). In...
Huge interest and demand on information superhighway have pressed various telecommunications research fronts and lead to a new form of future Internet consisting of wired and wireless segments where resource-constrained devices such as palm pilots and sensors may become integral parts of the Internet rather than access-only platforms. One of the key design problems is the security in such heterogeneous...
Internet Relay Chat (IRC) is a critical application in military networks for maintaining situational awareness and conducting battle management at all echelons. But these networks are often subject to frequent disconnections, limited bandwidth, and long delays, especially when using satellite services and field radios. Such conditions are inhospitable to TCP, and thus the standard IRC protocol, which...
