Description Wireless sensor networks can provide low cost solution to a variety of real-world problems. Sensors are low cost tiny devices with limited storage, computational capability and power. The large scale deployment of wireless sensor networks is expected to guarantee real time communication. Devices in sensor networks have a much smaller memory, constrained energy supply, less process and communication bandwidth. Topologies of the sensor networks are constantly changing due to a high node failure rate, occasional shutdown and abrupt communication interferences. Due to the nature of the applications supported, sensor networks need to be densely deployed and have anywhere from thousands to millions of sensing devices, which are the orders of magnitude larger than traditional ad hoc mobile networks. In addition, energy conservation becomes the center of focus due to the limited battery capacity and the impossibility of recharge in the hostile environment. With such a vast difference between traditional networks and sensor networks, it is not appropriate and inefficient to port previous solutions for ad hoc networks into sensor networks with only incremental modifications. In this thesis we studied the existing architecture of wireless sensor networks and came up with its limitations. To overcome the limitations of existing architecture and to improve the functionalities of sensor networks, we propose a new network architecture, which has a set of indispensable layers specially tailored to the characteristics of sensor networks. The layers of the proposed architecture are as follows: Physical layer with power management, Robust and self-stabilized MAC layer, Application independent data aggregation, Differentiated packet scheduling, Real time routing layer, Transport layer and Application layer. This proposed architecture will be an integrated solution and efficiently address the following important issues: _ Real-time communication _ Network congestion reduction and control
