DISTRIBUTED ALGORITHMS FOR CONSTRUCTING APPROXIMATE MINIMUM SPANNING TREES IN WIRELESS SENSOR NETWORKS --PARALLEL AND DISTRIBUTED SYSTEMS

While there are distributed algorithms for the minimum spanning tree (MST) problem, these algorithms require relatively large number of messages and time, and are fairly involved, making them impractical for resource-constrained networks such as wireless sensor networks. In such networks, a sensor has very limited power, and any algorithm needs to be simple, local, and energy efficient. Motivated by these ....etc

ABSTRACT
Colored Trees (CTs) is an efficient approach to route packets along link-or node-disjoint paths in packet-switched networks. her two trees, namely red and blue, are constructed rooted at a drain such that the path from any node to the drain are link-or node-disjoint. For applications where both the trees are used simultaneously, it is critical to maintain the trees after page link or node failures. this seminar discuss an algorithm, referred to as SimCT, that efficiently constructs and maintains colored trees under failures using only ....etc

1. INTRODUCTION
Today, there is a general consensus that, in the near future, wide area networks
(WAN)(such as, a nation wide backbone network) will be based on Wavelength
Division Multiplexed (WDM) optical networks. One of the main advantages of a WDM
WAN over other optical technologies, such as, Time Division Multiplexed (TDM)
optical networks, is that it allows us to exploit the enormous bandwidth of an optical
fiber (up to 50 terabits bits per second) with requiring electronic devices, which operate
at extremely high speeds.
