This paper presents a new adaptive mobility-aware MAC protocol for sensor NetWorks (MS-MAC). The protocol uses any change in received signal level as an indication of mobility and, when necessary, triggers the mobility handling mechanism. By doing this way, the new mobility-aware MAC protocol can work very energy-efficiently when the NetWork is stationary, whereas it can maintain some level of NetWork performance when there are mobile sensors.

nesc language introduction. nesC is an extension to C [2] designed to embody the structuring concepts and execution model of TinyOS [1]. TinyOS is an event-driven operating system designed for sensor NetWork nodes that have very limited resources (e.g., 8K bytes of program memory, 512 bytes of RAM). TinyOS has been reimplemented in nesC. This manual describes v1.1 of nesC, changes from v1.0 are summarised in Section 3.

The task in this assignment is to implement an airline routing system. Your system should be able to read in a ight NetWork as a graph from a le, where airports are represented as vertices and ights between airports are represented as edges, take as input two airports and calculate the shortest route (ie path) between them.

In the next generation of wireless communication systems, there will be a need for the rapid deployment of independent mobile users. Significant examples include establishing survivable, efficient, dynamic communication for emergency operations, disaster relief efforts, and military NetWorks. Such NetWork scenarios cannot rely on centralized and organized connectivity, and can be conceived as applications of mobile ad hoc NetWorks. A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the NetWork topology may change rapidly and unpredictably over time. The NetWork is decentralized, where all NetWork activity including discovering the

在图形中若于个边(edge)上加上一些值,此数值称为比重( weight ) 。而此图形称为比重图形(Weight Graph ) ,若weight是成本( cost )或距离( distance ) ,则称此图形为网路( NetWork )。根据Spanning Tree的定义,知一个图形可有许多不同spanning tree ,在NetWork中找出一个具有最小成本( Cost )的Spanning tree ,则此Spanning tree称为最小成本生成树。
