String matching is a basic problem of computer science and it has been widely used in many important application fields. To date, QF is one of the fastest exact single pattern string matching algorithms for long patterns. In this paper, we improved the QF algorithm by introducing the greedy jump method and gained a serial of exact single pattern string matching algorithms named Greedy QF. Experimental results indicated that Greedy QF is faster than QF in most of case and Greedy QF is faster than other known algorithms in many cases for long patterns on our platform.

String matching is a fundamental problem in computer science. It has been widely used in many important fields. In this article, we presented an integer comparison method to improve the branch performance, and we improved an exact single pattern string matching algorithm-TSW by introducing the multi-window method and the integer comparison method. Therefore, we presented a new serial of algorithms named kSWXC (k Sliding Windows with X Comparison, X is the data type for comparison). Experiment results indicated that kSWXC is faster than other known algorithms for short patterns on our platform.

In Wireless Sensor Network (WSN), the ability to avoid collision directly impacts on node energy consumption and network performance. Based on introduction of CSMA/CA protocol, the paper laid emphasis on shortcoming of binary backoff algorithm affect survivability time of WSN. On this basis, a kind of CSMA/CA protocol based on improved binary backoff algorithm was proposed. The algorithm reasonably scheduled competition and backoff time of nodes and improved fairness of the network to increase network survival cycle. Network simulation results with OPNET shows that the improved protocol effectively improves network survivable cycle in case of fixed network size. The performance of network delay and throughput also improved to a certain extent.
The main purpose of the Joint Detection (JD) techniques is an accurately estimating the user's signal, the difficulty lies in the system matrix inversion, so to find the fast inversion algorithms is the main key t...

According to several attributes of network structure, firstly, we give a summary about some related works of network stability. And then, through the simulation experiments, we explored the influence of network density and network size on the stability of complex networks and got some interesting conclusions. Finally, we defined a factor η for the connection strength of community, and we speculate that there is a threshold η c , it led to the network stability decreased and then increased with the increase of η, and eventually reached a peak.
