Ieee 802.15.4 Standard

Internet of Things (IoT) is a promising technology that uses wireless sensor networks to enable data collection, monitoring, and transmission from the physical devices to the Internet. Due to its potential large scale usage, efficient routing and Medium Access Control (MAC) techniques are vital to meet various application requirements. Most of the IoT applications need low data rate and low powered wireless transmissions and IEEE 802.15.4 standard is mostly used in this regard which offers superframe structure at the MAC layer. However, for IoT applications where nodes have adaptive data traffic, the standard has some limitations such as bandwidth wastage and latency. In this paper, a new superframe structure is proposed that is backward compatible with the existing parameters of the standard. The proposed superframe overcomes limitations of the standard by fine-tuning its superframe structure and squeezing the size of its contention-free slots. Thus, the proposed superframe adjusts its duty cycle according to the traffic requirements and accommodates more nodes in a superframe structure. The analytical results show that our proposed superframe structure has almost 50% less delay, accommodate more nodes and has better link utilization in a superframe as compared to the IEEE 802.15.4 standard.

Leach Protocol

The zone of wireless sensor networks (WSNs) is one of the developing and quickly developing fields in the logical world. This has realized growing ease, low-control and multiwork sensor hubs. Nonetheless, the real certainty that sensor hubs come up short on vitality rapidly has been an issue and numerous vitality effective directing conventions have been proposed to take care of this issue and safeguard the life span of the network. The proposed EEDBLEACH chooses bunch head with most elevated leftover vitality in every communication round of transmission and furthermore considers, the briefest good ways from the base station to the hubs in the group. By accepting the separation as a parameter which diminishes the vitality utilization. The EEDBLEACH Protocol is correlation with the current LEACH convention. Reproduction results demonstrate that EEDBLEACH Protocol drags out the lifetime of the network
