1.According to a pipeline project of Qingdao Petr-chemical Plant,how to use a few of different communication protocols such as DH+、DF1、Ethernet,MODBUS,OPC in a SCADA system is described and a brief introduction on the main feature of each protocol and the convenience to the end user is ...
However, the communication paradigms in WSNs differ from the ones associated to traditional wireless networks, triggering the need for new communication protocols. In this context, the IEEE 802.15.4 protocol presents some potentially interesting features for supporting large-scale ubiquitous computing ...
etc. Designing routing protocols for such a network is challenging because apart from an efficient and high-performance technique, low energy and resources factors also need to be considered[1]. Various factors that influence the routing protocol design are wireless means of communication, energy stor...
Instead of that, this work is intended for becoming a platform for testing different routing protocols in UAV networks. This work uses the IEEE 802.11s standard. In [54], an aerial network consisting of 5 UAVs uses the IEEE 802.15.4 standard. The UAVs, which are equipped with XBee Pro ...
Wireless sensors need data that arrive in time. This demand is fulfilled by a real-time communication for applications that use WSN technologies. The protocols, TCP and UDP, were not designed for real-time communication in wireless networks. The proposed protocol can manage data unit delays by ...
In fact, the client should not need know the number of processes in the group or even that there are multiple processes. Group communication mechanisms and protocols facilitate the maintenance of a group of processes that cooperate to perform some service. Typically, service groups will need to ...
