چکیده (انگلیسی):
The packet scheduling is essential and plays an important
role to sense the element nodes with resource constraints in Wireless
Networks. The packet scheduling scheme also scale the energy
consumption and end-to-end information transmission delay in time
period and non-real-time information packets during wireless
transmission. The proposed Priority based Packet Scheduling (PPS)
technique has a tendency to overcome the issues based on priority
queues in a wireless network. The priority queue has three levels at
each node, except those at the last virtual hierarchy level in the zonebased
topology of wireless network. In the meantime packet square
are measured and placed in the highest-priority queue and might preempt
information packets in alternative queues. In the non-real-time
period packet square are measured and placed into two alternative
queues supported at a particular threshold of their calculable interval.
The time period and non-real time information has two queues in a
leaf node, since they did not receive information from alternative
nodes which causes scale back end-to-end delay. The proposed PPS
technique has affinity to evaluate performance through simulations
for the time period and non-real-time information. Simulation results
illustrate that the PPS Scheme outperforms typical schemes in terms
of average information waiting time and end-to-end delay.
