Sliding Window Protocol Introduction: Sliding window protocol is used where a reliable transmitting of frame is required. It relies on packeting the frame queue to a definable window size which is provided to sender and receiver. Sliding window protocol defines maximum transmitter window size‚ Ws which is always one less than the sequence number. How transmitter window is defined: It is contains the data that are ready to be send. The lower limit in transmitter window which is waiting for

Collision-Free MAC Protocol for Wireless Sensor Networks Muneeb Ali‚ Tashfeen Suleman‚ and Zartash Afzal Uzmi Computer Science Department‚ LUMS {muneeb‚tashfeens‚zartash}@lums.edu.pk Abstract Mobility in wireless sensor networks poses unique challenges to the medium access control (MAC) protocol design. Previous MAC protocols for sensor networks assume static sensor nodes and focus on energyefficiency. In this paper‚ we present a mobilityadaptive‚ collision-free medium access control protocol (MMAC) for

Chapter 4 Network Layer and Routing 1) What are the two main functions of a datagram-based network layer? What additional functions does a VC-based network layer have? 2) List and describe the ATM network service models. 3) Compare and contrast link-state and distance-vector routing algorithms. 4) Discuss how a hierarchical organization of the Internet has helped to scale to millions of users. 5) It is necessary that every autonomous system use the same intra autonomous routing algorithm? Why or why

constraints. In the past decade‚ significant effort has been devoted to QoS routing design which fails to obtain a one-for-all solution for MANETs. The key reason‚ it is believed‚ is the application dependent nature of routing protocols. Moreover‚ few researchers consider the relative importance of QoS metrics. Last but not the least‚ performance metrics are compared independently without any conclusion indicating the optimal protocol in a given scenario. In this paper‚ a QoS based performance evaluation

The KYOTO Protocol The Kyoto protocol is an international agreement linked to the United Nations Framework Convention on Climate Change. The major feature of the Kyoto protocol is that it sets binding targets for 37 industrialized countries and the European community for reducing greenhouse gas (GHG) emissions. These amount to an average of five percent against 1990 levels over the five year period 2008-2012. The major difference between the Protocol and the Convention is that while the Convention
