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

"Realistic Broadcast Protocol Handler (RBPH) is a reliable multicast transport protocol mainly aimed for applications that require ordered‚ duplicate-free‚ multicast data delivery from multiple sources to multiple receivers. The advantage of RBPH over traditional multicast protocols is that it guarantees that a receiver in the group either receives all data packets from transmissions and retransmissions‚ or is able to detect unrecoverable data packet loss. RBPH is specifically intended as a workable

following 3 questions as per assignment; QUESTION 1 – What are the three primary differences between Cisco layer 2 network resiliency and HP IRF resiliency? The first obvious difference is the protocols that they use. Cisco uses Spanning Tree Protocol (STP) while HP IRF uses the Link Aggregation Control Protocol. The second difference lies in the architecture being used. Cisco uses a mesh of network switches‚ linked to other switches in the aggregation layer‚ which in turn is linked to the core. This

Internet protocol suite The Internet protocol suite is the set of communications protocols used for the Internet and similar networks‚ and generally the most popularprotocol stack for wide area networks. It is commonly known as TCP/IP‚ because of its most important protocols: Transmission Control Protocol(TCP) and Internet Protocol (IP)‚ which were the first networking protocols defined in this standard. It is occasionally known as the DoD model due to the foundational influence of the ARPANET

What is WAP? WAP stands for Wireless Application Protocol. The idea has been developed by some of the wireless telecommunications giants such as Nokia and Ericsson. The Wireless Application Protocol (WAP) uses the Internet as a gateway for the transmission of the protocol. WAP has brought the Internet and the sub-services that it provides right into our lives as we are on the move. WAP brings us information right to the screen of our mobile phone. WAP offers the possibility to call specific

FTP File Transfer Protocol (FTP) is a standard network protocol used to transfer files from one host to another host over a TCP-based network‚ such as the Internet. FTP is built on a client-server architecture and uses separate control and data connections between the client and the server.FTP users may authenticate themselves using a clear-text sign-in protocol‚ normally in the form of a username and password‚ but can connect anonymously if the server is configured to allow it. For secure transmission
