An Improved Performance Analysis Of Priority Scheduling Algorithm In Modified Ad Hoc Grid Layer

R Bhaskaran
2012 International Journal of Distributed and Parallel systems  
An improved performance analysis of priority based scheduling algorithm for the ad hoc grid layer is presented in this paper.  ...  A priority queuing model is developed to reduce the execution time of the jobs. Here, jobs to be dispatched based on priority. Execution time is one prime metric proposed for the system.  ...  The scheduling is a complex process and have focused on global scheduling dealing with clusters.

Machine-to-Machine Communications: Architectures, Standards and Applications

Min Chen
2012 KSII Transactions on Internet and Information Systems  
As a new business concept, machine-to-machine (M2M) communications are born from original telemetry technology with the intrinsic features of automatic data transmissions and measurement from remote sources  ...  Furthermore, the progress of global M2M standardization is reviewed, and some representative applications (i.e., smart home, smart grid and health care) are given to show that the M2M technologies are  ...  The rationale behind M2M communications is based on two observations: 1) a networked machine is more valuable than an isolated one; 2) when multiple machines are interconnected, more autonomous and intelligent  ...
