The protocol is hierarchical and cluster based from network structure perspective. Each cluster contains one cluster head node and two deputy cluster head nodes. The re-clustering time and energy has been minimized

For such systems, a system state model is important not only for understanding the behavior of the system, but also for test case design, test coverage analysis, maintenance, etc. However, developers rarely construct the system state model for practical systems because it is usually too complex and cumbersome to construct. On the other hand, developers

The particle is updated not only by the best position in history (pbest) and the best position among all the particles in the swarm (gbest), but also using the position that is nearest neighbor of pbest. Additionally, we introduce a modified PSO algorithm based on the fuzzy clustering of particles to communication with the nearest neighbor for reducing the premature convergence and in sequel enhance the capability of global exploration. We validate our methods by an extensive experimental study on four benchmark test functions and compare the result with basic PSO.

In this paper, we present a dynamic soft real-time task scheduling algorithm named DDSCHED for distributed systems. The two main components of DDSCHED are a local scheduler and a distributed scheduling scheme. The local scheduler is designed based on the earliest deadline first(EDF) policy and the concept of window. The implementation uses an efficient
