Li T, Fei M, Hu H (2010) Performance analysis of industrial wireless network based on IEEE 802.15
We consider the total available bandwidth to be of approximately 25700 bytes/sec, accounting for the overhead of 19.6% introduced by IEEE 802.15
.4 on the total bandwidth available for CoAP communications.
Indeed simulations results are carried out over CM1 IEEE 802.15
.3a channel model.
The coding scheme in IEEE 802.15
.4 has built in redundancy, which makes the communication robust, allows us to detect losses, and enables the retransmission of lost packets.
The IEEE 802.15
.4 requires transmission and reception at 2.4 GHz worldwide within the MAC layer and the 868 MHz and 915 MHz bands in the European and American markets respectively, according to the IEEE 802.15
WPAN[TM]--Task Group 4 (TG4).
Assume that the signal was transmitted in two typical channels: one is AWGN channel without ISI and the other is IEEE 802.15
.3a multipath channel and the multipath signal is processed by a selective-RAKE (SRAKE) receiver with 8 branches and using MRC (Maximal Ratio Combining) rule.
Additionally, smart meters to be deployed in several countries are required to be certified for compliance with the latest specifications including G3-PLC, PRIME and IEEE 802.15
.4 is a standard for low rate and low power wireless communication (Petrova et al, 2006) to implement these sensors because of its low duty cycle and self-organization.

* Based on IEEE 802.15
.4e, it creates full-mesh networks (mesh-to-the-edge).
- Supported standards: 802.15

Therefore, there are increasing research and standardization efforts, such as time-synchronized mesh protocol (TSMP) , IEEE 802.15
.4e, ISA100.11a, WirelessHART, and other related protocols, into developing multi-channel communications protocols.
