1 Multi-Channel Scheduling and Spanning Trees: Throughput-Delay Trade-off for Fast Data Collection in Sensor Networks ¨ Amitabha Ghosh‚ Ozlem Durmaz Incel‚ V. S. Anil Kumar‚ and Bhaskar Krishnamachari Two primary factors that affect the data collection rate (throughput) and timeliness (delay) are: (i) efficiency of the link scheduling protocol‚ and (ii) structure of the routing tree in terms of its node degrees and radius. In this paper‚ we utilize multiple frequency channels and design an

spite of the advantages afforded by social networking sites they can have potentially harmful effects. It is undeniable that social networks have a lot of advantages; still they also have several disadvantages. It is common knowledge that many people‚ especially young people‚ have heard about or belong to at least one social networking site. Social networks’ users rely on these sites to maintain their social relations and entertain themselves. It seems that these networking sites offer many advantages

Network Hardening Unit 8 Assignment 1 It is very important to go through the process of hardening. Hardening is where you change the hardware and software configurations to make computers and devices as secure as possible. I picked the network layout 1-the workgroup . First with the workstations and laptops you need to shut down the unneeded services or programs or even uninstall them. I would also have some good anti-virus software on the workstations. You also need a hardened image for

indicate that the method suggested has an ideal level of security. With development of computer networks and the increasing use of Internet‚ the discussion of security in transferring data has been put forward as one of important subjects. The reason for it is the accessibility of data in Internet‚ and their easy access by authorized and unauthorized people. Data packets in Internet pass several intermediate public networks before they reach the target; this makes it easy that other people access data.

Premium IP address Data type
Network Security Some DoS attacks can be avoided by applying vendor patches to the software that has been compromised. Another way to deal with DoS attacks in the case of an attack coming from a number of known IP addresses is to put up a rule to drop all incoming traffic from those known attackers. Yet another way to deal with these types of attacks is to set up packet filters. This will act as a proxy for connections. Once the handshake is validated it will be forwarded to the correct destination

rate of more than one instruction per cycle is difficult to achieve. This case study uses multi bit scoreboard architecture to handle data conflicts for out of order execution and completion of instructions. The paper analyses the performance of the superscalar microprocessor by using two stimulation models which uses benchmark programs and one calculation model which uses queuing networks to derive the formula for data deficiencies from the peak performance. Introduction The single bit scoreboard
