As a novel information acquiring and processing technology, compared to other traditional sensor networks, wireless multimedia sensor networks pay more attention to the information-intensive data (e.g. audio, video, image). Potential applications of wireless multimedia sensor networks span a wide spectrum from military to industrial, from commercial to environmental monitoring, This paper discusses qosrouting problem model with multiple qos constraints, which may deal with the delay, delay jitter and bandwidth, and presents qos routing algorithm with multiple constraints based oil genetic algorithm, and gives the algorithm idiographic flow. Simulating results show that higher routing successful ratio and faster convergence is achieved in the algorithm.

At present, network environment follow protocol standard of IPV4 is intended to do the best effort of network to provide network applied service for users, however, not caring about service *** the packet loss rate is high, it cannot reach an ideal applied results. This article through the establishment of mathematical model, put forward a new distributed multi qos routing algorithm, given the realization process of this distributed qos routing algorithm, and simulation was carried out by simulation software. The results show the proposed algorithm can improve the utilization rate of network resources and the service quality of network application.

Smart grid is an emerging technology which is able to control the power load via price signaling. The communication between the power supplier and power customers is a key issue in smart grid. Performance degradation like delay or outage may cause significant impact on the stability of the pricing based control and thus the reward of smart grid. Therefore, a qos mechanism is proposed for the communication system in smart grid, which incorporates the derivation of qos requirement and applies qosrouting in the communication network. For deriving the qos requirement, the dynamics of power load and the load-price mapping are studied. The corresponding impacts of different qos metrics like delay are analyzed. Then, the qos is derived via an optimization problem that maximizes the total revenue. Based on the derived qos requirement, a simple greedy qos routing algorithm is proposed for the requirement of high speed routing in smart grid. It is also proven that the proposed greedy algorithm is a K-approximation. Numerical simulation shows that the proposed mechanism and algorithm can effectively derive and secure the communication qos in smart grid.
