Algorithm for solving time table questions based on GA

Time table problem is a multifactor optimized decision problem and is typical problem in constitution and planning. It has been proved as a kind of NP-complete problem. Genetic Algorithm (GA) is based on the biological mechanism of natural selection and heredity, leveraging colony searching technology, and is particularly applicable for the resolution of complicated on-linear problems intractable with traditional searching methods. This paper designs the genetic arithmetic about the time table problems, a new method chromosome encoding is designed. This method mainly aims at in the test time arrangement the concrete question to propose each kind of corresponding heredity operation strategy. The experiment proved this algorithm in the test time cell and the examination place number is all not in the very big situation, reduced the average evolution algebra enormously, and can guarantee obtains the overall situation optimal solution in the two number random situation.

DiffServ-aware MPLS traffic engineering

This article mainly introduced the QoS and its three service models: Best-Effort, IntServ and DiffServ. This article put emphasis on discussing the MPLS traffic engineering with differentiated services. Its core concept is that map the DSCP zone of IP message to the label zone of MPLS message, then make the MPLS traffic engineering consider the DiffServ factor when the network computing and choosing paths, which not only fully utilizes the link paths bandwidth, but also realizes the QoS pledge to network traffic.

Research on the mobile wireless net based on the IPv6 protocol stack

In the IPv4 wireless network, the quality of the communications between the wearable computers or the mobile nodes is slow and the wearable computers cannot achieve in the sub-seamless switching between LANs. According to the three function entities of mobile IPv6 the protocol stack software is divided into three major modules, and proposed design program and the division of sub-module based on the wireless net which is consist of wearable computers.

Research on the Developed Intelligent Mobile Agent Communication Model in Wearable System

Traditional wearable systems cannot communicate the location with the condition of people instantly, dynamically and accurately and it is also in low-speed, high-latency and unreliable; the system configuration information with location needs to be changed frequently. By emulating a distributed arithmetic, it analyzes the load of the communication network, the average time that the mobile agent has to move and the average time that the mobile agent has to carry every movement process out.

An Improved Way of Multicast in Wearable WSN

Modern wearable system requires users to transmit their own information of exact location and physical characteristics timely. It is required to reduce the network delay and excessive energy consumption, which are caused by network code in wearable WSNs. A fast random linear mechanism of network coding based on nodes collaboration is introduced. Energy consumption of nodes is reduced by transmitting the initial code of the node, and transmitting linear independent packets received merely. After gathering node coding, ACK return along the best path to reduce the network delay. Simulation results show that delay of data transmission is reduced greatly by introducing random linear network coding for sensor network, and the improved coded mode balances the network load.

Research of Opportunistic Routing Protocol in Wearable Sensor Network

Because the unstable wireless transmitting channel in wearable system, this article researched the broadcast characteristics of information channel in wearable wireless sensor network, and proposed a opportunistic routing protocol based on random linear network coding. This protocol used the distance unstable chain which can not be used by traditional route protocol. It requires each node except for destination in network to transmit the random linear combination created by all packets in buffer, and confirms the expected number of transmissions according to node’s credit value which is computed by a heuristic algorithm. The experiment results show that the proposed protocol presents significant performance improvements, especially in network throughput and end-to-end delay.
