Special Issue Information

Dear Colleagues,

Networked computers and Internet formed the biggest working machine ever made by human.  Applications for this machine are enormous and amount of them growing.

Regretfully, vast majority, if not all of them, is about to make our life more convenient, comfortable, easier, and not making human better, healthier or safer.  I have a feeling that we all do “what we can” instead of “what we have to…”

The latter ones require substantially different properties of this machine: using networked computers for real time monitoring of nuclear reactor, air-traffic control, health monitoring, other real-time and safety critical missions requires serious reshuffle of the whole world of connected computers (CC).

Thus making shift to real-time safety critical use of  CC we have to redo our system software toward real-time fault tolerant functioning, our links to make more reliable and resilient, our computers, especially serving for communication ones - routers to be fault tolerant and available at order of magnitude higher than today. What can we do to make it shift??

Threesome answer is proposed:

 

  1. Routing algorithms should be analyzed and redone where necessary to be able to operate with hardware degradation with minimum or no losses of availability for CC system as a whole
  2. Router hardware has to be redesigned with performance-, reliability- and energy-wise (PRE) properties for CC systems
  3. Protocols known and future ones should be re-designed or designed from scratch addressing mentioned properties of the whole system and its main elements.

 

Primarily, we have to achieve extreme availability of backbones of CC world – routers, making them fault tolerant, with no degradation in performance or overheads in power consumption.

Clear, it is easier to say that to do.  Clear, all actions and solutions proposed to address bullet points above should be accompanied by analysis of gains in PRE properties.

Reducing energy consumption of sensor nodes to prolong the lifetime of finite-capacity batteries and how to enhance the fault-tolerant ability of networks are the major challenges in design of Wireless Sensor Networks (WSNs). In this paper, we present an energy-efficient system of WSNs for black pepper monitoring in tropical areas. At first, we optimized the base station antenna height in order to facilitate reliable communication, after which the Energy-efficient Sensor Protocol for Information via Negotiation (ESPIN) routing protocol was utilized to solve the energy saving challenge. We conducted radio propagation experiments in actual black pepper fields. The practical test results illustrate that the ESPIN protocol reduces redundant data transmission and whole energy consumption of network, and enhances the success rate of data transmission compared with traditional Sensor Protocol for Information via Negotiation (SPIN) protocol. To further optimize topology for improving the network lifetime, we designed a symmetrical double-chain (SDC) topology which is suitable to be deployed in farmland and compared the lifetime with traditional tree topology. Experiment results indicate SDC topology has a longer network lifetime than traditional tree topology. The system we designed will greatly help farmers to make more informed decisions on the efficient use of resources and hence improve black pepper productivity. Full article

An approach to consider computers and connected computer systems using structural, time, and information redundancies is proposed. An application of redundancy for reconfigurability and recoverability of computers and connected computer systems is discussed, gaining performance, reliability, and power-saving in operation. A paradigm of recoverability is introduced and, if followed, shifts connected computer systems toward real-time applications. Use of redundancy for connected computers is analysed in terms of recoverability, where two supportive algorithms of forward and backward tracing are proposed and explained. As an example, growth of mission reliability is formulated. Full article
