Self-organization is an important issue in wireless sensor networks because of the inherent unreliability of the network. Besides, variable threats in the networks can not be ignored. Extending battery life and enhancing robustness under variable threats are two essential aspects which need to be considered when a self-organization scheme is explor...

... with different parameters produced similar results. A typical set of results is presented here. There were 100 sensors with three cluster heads and sensor density is 8. The sensors were arranged in a 10 × 10 matrix. Fig. 9 shows the total battery consumption without proposed scheme and Fig. 10 shows the total consumption under the same circumstance but with self-organization scheme ...

Summary Spam detections fall into two categories: rule-based and statistical-based. The former refers to the detection which is performed by looking for spam-liked patterns in an email. Since the rules can be shared, they have been popularized quickly. The rules, however, are built manually it is hard to keep them up with the variation of spam. The...
Today many services can be requested via network by sending an electronic message to the service provider. If the data is coded in syntax "understandable" to computers, it is possible to automate its interpretation, elaboration and storage, thus speeding up data processing and reducing human error. Digital signature can be associated with Internet...
This paper presents a new language called APSL for formally describing protocols to facilitate automated testing. Many real world communication protocols exchange messages whose structures are not trivial, e.g. they may consist of multiple and nested fields, some could be optional, and some may have values that depend on other fields. To properly t...
Protein secondary structure and solvent accessibility predictions are a fundamental intermediate step towards protein structure and function prediction. We present new systems for the ab initio prediction of protein secondary structure and solvent accessibility, Porter 4.0 and PaleAle 4.0. Porter 4.0 predicts secondary structure correctly for 82.2%...

Wireless sensor networks constitute a special group of distributed measurement systems that are increasingly used to observe environmental factors for civilian or military purposes. These observations are not conducted by a single node, but rather by multiple nodes which together form ad-hoc cooperation networks. The event to be measured can be observed with the benefit of the very working principle of sensor networks, where information from each node is transmitted to the observer in the form of an induced periodic query or is induced by the event. With the technological advancements it is now possible to manufacture nodes whose size is in the order of centimeters. This enables the use of sensor nodes on an unprecedented scale and opens new opportunities for so-called ubiquitous computing. Initially, sensor networks were wired solutions. The development of wireless and data processing technologies has helped sensor nodes to take over a larger area of research. The authors of this article wish to raise the issue of sensor networks development and show the influence of various factors on the self-positioning of sensor networks.
Nowadays wireless sensor networks have gained much popularity due to their flexibility. This progress has enabled the use of sensor nodes on an unprecedented scale and opened new opportunities for the so-called ubiquitous computerization. The total freedom of nodes distribution within the wireless sensor network (WSN), where the wireless characteristic is one of the greatest advantages of WSN, implies its greatest weaknesses. To overcome this challenge specialized routing protocols, such as many different version of LEACH, were ushered in so as to make effective use of the energy of the nodes themselves. This article aims to show the functioning of a new author’s solution, called IIS-LEACH, which uses redundancy as a basic element in increasing the reliability of WSN networks.
