© 2019 IEEE.Using the IEEE 802.15.4 could be notice in various areas such as hospitals, agricultural, industrial, as well as smart homes. All the above-mentioned areas require devices that have a mechanism that consume low energies and low costs for communication. Thus, the purpose of fulfilling the needed requirements, IEEE 802.15.4 could be seen as effective and commercial solution. Various factors exist for studying the efficiency related to the wireless networks. Emulation could be define as a toll of high importance for designing and evaluating the implementation and the efficiency related to protocols, while the majority of real applications are considered to be of high difficulty with regard to the real applications. Concerning the presented paper, the main aim has been showing performance results, which are relates to IEEE 802.15.4 through use of octave simulations. The main task of the presented paper is analyzing the protocol's performance in various conditions as well as having the ability of checking the performance with regard to reliability in real-Time. One of the aims of this study is analyzing the performance parameters, that are energy consumption rate, packet received ration as well as the Received Signal Strength Indicator (RSSI). All of the mentioned parameters studied in indoor and outdoor conditions the purpose of verifying the performance of the wireless protocol. The presented paper focus on 2 nodes in for the peer-To-peer communications, where one of the nodes acts as base-station or coordinator, while the other node is considered as router. The router include Xbee with sensors and Arduino, while the coordinator consist of Xbee receiver and adapter.
