In this paper, real time performances of process level networks based on IEC61850 SCSM (Specific Communication Service Mapping) Model are analyzed. IEC61850 SCSM Model which is different from Ethernet OSI (Open System Interconnect) Model of Ethernet is introduced by IEC61850. Firstly, dominating factors of real time performances of process level networks are studied. Then IEC61850 SCSM Model is amplified...
Bluetooth is a key connectivity technology for the deployment of wireless Personal Area Networks as far as it is the most popular low power communication feature incorporated in devices such as laptops or smartphones. This paper proposes an analytical model to predict the delay of the transmissions in Bluetooth piconets employing Serial Port Profile (SPP), which is massively implemented by Bluetoothenabled...
DCF (distributed coordination function) of IEEE802.11 MAC protocols uses binary exponential increasing mechanism, called BEB (binary exponential backoff) algorithm. Due to the lack of a mechanism evaluating the channel condition, it can not tune the value of contention windows adaptively, according to the actual network traffic. By introducing the network allocation vector count in routing protocol...
There are few approaches for the delay analysis of ARQ in underwater acoustic links owing to the fact that only the worst efficient SW-ARQ can function over the half-duplex channel. Meanwhile, many approaches for the delay analysis of the most efficient SR-ARQ in terrestrial communications have appeared to be impractical because of the static channel assumption and/or much high computational complexity...
Bluetooth is by far the most employed technology to develop practical applications of Wireless Personal Area Networks (WPAN). This paper studies the performance of Bluetooth transmissions that make use of the Bluetooth PAN (Personal Area Network) profile. In particular, the study offers an analytical model that defines the optimal bound for the end-to-end data delay. The proposed dasiadelay budgetpsila...
