The IEEE 802.11 protocol family provides up to 54-Mbps data rate, whereas the industry is seeking higher data rates. This paper shows that a theoretical throughput upper limit and a theoretical delay lower limit exist for the IEEE 802.11 protocols. The existence of such limits indicates that by simply increasing the data rate without reducing overhead, the enhanced performance, in terms of throughput and delay, is bounded even when the data rate goes into infinitely high. Reducing overhead is vital for good performance.

Abstract Providing wireless coverage to users using Unmanned Aerial Vehicles (UAVs) encounters two major challenges: deployment and channel allocation. To this end, solutions to both issues are proposed in this paper. An overloaded UAV attempts to acquire more channels by performing channel bonding/aggregation followed by requesting its chosen peers to move closer for load sharing. The proposed channel reallocation schemes minimize interference caused by channel reassignments, or change in netwo...

Currently, a variety of wireless modules are purposed for different criteria in the area of the agricultural internet of things; however, there is a lack of appropriate methods enabling these wireless modules to operate in the same frequency band. The goal of this paper is to make a very thorough quantitative analysis on the theoretical maximum collision time and collision probability of WiFi or Bluetooth network with RFID interferers. We propose the interference avoidance scheme which requires ...

Recently, several projects for cooperative intelligent transportation systems (C-ITS) are being actively conducted all over the world. The C-ITS is expected to secure the safety of road traffic and provide more convenient transportation services to drivers. The dedicated short range communication (DSRC) technology is a vehicle communication technology developed for the purpose of providing an ITS service. So far, many studies and field tests using a DSRC technology have been conducted. However, ...

This paper considers an infinite buffer renewal input queue with multiple working vacation policy wherein customers are served by a single server according to general bulk service (a, b)-rule (1 ≤ a ≤ b). If the number of waiting customers in the system at a service completion epoch (during a normal busy period) is lower than ‘a’, then the server starts a vacation. During a vacation if the number of waiting customers reaches the minimum threshold size ‘a’, then the server starts serving this bat...

In this paper, we analyze the relationship of number of access point (AP) and achieved throughput for a given scenario. In the scenario, we consider a number of parameters, i.e. given area, topology, number of users, expected rate and channel allocation vector. We find that in general with the increase of AP the performance of overall network improve. However, after a certain number of deployed APs, further increase of AP does not bring substantial improvement in the network performance. More sp...

The applications for MANETs have increased rapidly and today MANETs are capable of providing a variety of services. One of the major contributing factors is the availability of radios that are able to adapt to the channel conditions and can transmit at multiple data rates. A common approach for channel access is to employ a CSMA/CA based mechanism. However, these protocols tend to under perform at heavy loads or due to exposed/hidden nodes. One solution to this problem is to use a scheduling bas...

The miniaturization of wireless sensors and medical devices have empowered the extension of Wireless Body Area Networks (WBANs) and E-Health care systems. However, in WBANs, wireless communications are exposed to a variety of passive and active security attacks. As a result, protection of privacy and integrity of the collected data from WBANs is of high importance. To mitigate these problems, numerous key management and security solutions have been designed for the WBANs in the literature, that ...

Accountability in computing implies that an entity should be held responsible for its behaviors with verifiable evidence. In order to study accountability, quantitative methods would be very helpful. Even though there are some researches in accountability, there are no other works which study quantitative accountability in practical settings, while quantitative accountability is defined as using quantities or metrics to measure accountability. In this paper, we propose P-Accountability, which is...
