A Mechanism to Improve the Performance of Zone-Based Broadcasting Protocol in the Recovery Phase

چکیده
Wireless Sensor Networks (WSNs) have been widely used in environment monitoring to collect useful information. Packet broadcasting is an essential communication behavior for establishing a communication path from sink node to an interested region of sensor nodes. ZBP is a cellular based broadcast protocol, and it successfully outperformed simple flooding manner broadcasting and common cellular based approach in two main aspects: first it reduced the number of sensor nodes that forward transmission packets and thus save energy consumption; second, it can efficiently avoid collision by properly arranging broadcasting schedule. However it still faces broadcasting failure caused by blank region of sensors. This paper improves ZBP by introducing an energy efficient recovery mechanism which recovers broadcasting when blank region interrupts the request forwarding. Compared with the simple over-network flooding recovery used by ZBP, our proposed protocol can reduce much energy consumption.

Phase-Destabilization Mechanism of Polymer-Modified Bitumens in Quiescent Annealing
Bitumen as a binder in coating and insulating materials is modified with polymers to improve its performance in service conditions. Almost all polymers are incompatible with bitumen, and at high temperatures due to relatively very low viscosity of the bitumen phase, are separated from it. These lead to a considerable limitation in the use and handling of polymer-modified bitumens. An understand...

Broadcasting is one of the most fundamental operations in mobile ad hoc networks. Broadcasting serves as a building block in many routing protocols. The simplest approach for broadcasting is flooding. However, it generates many redundant messages that cause to loss of scarce resources such bandwidth and battery powers and it may lead to contention, collision and extreme decrease of network perf...

Due to the increase of users the efficient usage of spectrum plays an important role in digital terrestrial television networks. In digital video broadcasting, local and global content are transmitted by single frequency network and multifrequency network respectively. Multifrequency network support transmission of global content and it consumes large spectrum. Similarly local content are well ...
