[Other resource] ExceptionalC++Style40NewEngineeringPuzzles

Description: 这本也是经典中的经典。它已经深入到接触 C++ Object Model 的层次。特别是 Exception-Safety 这一章一系列的步步深入，很大程度上改变了我对 C++ 的认识。此外，它有提到 Pimpl Idiom，这对改善 C++ 编译效率也有一定的帮助。其他的主题，例如泛型编程和对标准库的几个讨论议题、暂时物件、物件寿命、自动转换…等，也颇有深度。如果没看过这本，且对自己的 C++ 功力颇有信心的人，可以测试看看。 -This is the classic classic. It has in-depth exposure to C Object Model level. Especially Exception-Safety of this chapter a series of in-depth step by step. I changed to a large extent on C awareness. Moreover, it mentioned Pimpl Idiom, to improve the efficiency of the C compiler is also helpful to a certain extent. Other themes, such as Generic programming and the standards of several topics for discussion, temporary objects, object lifetime, automatic conversion, etc. quite deep. If they read this, and C for their skill very confident in, we may look at the test.

Description: WSNs being energy constrained systems, one major problem is to employ the sensor nodes in such a manner so as to ensure maximum coverage and connectivity with minimal or optimal number of nodes and furthermore elongate network lifetime with maximum energy utilization. The problem addressed has been tackled for 1-D linear array and further extended to 2-Dimensions as stated in the next slides. -WSNs being energy constrained systems, one major problem is to employ the sensor nodes in such a manner so as to ensure maximum coverage and connectivity with minimal or optimal number of nodes and furthermore elongate network lifetime with maximum energy utilization.

[Program doc] A-new-clustering-method-to-prolong-the-lifetime-o

Description: One of the most critical issues in the wireless sensor networks is the network s nodes limited availability of energy. The network lifetime strictly depends on its energy efficiency. Clustering is a method to make the consumed energy efficient. LEACH is one of the fundamental clustering algorithms. In this paper we have proposed an algorithm which extends LEACH by considering number of neighbors and remaining of the energy of each node to be a cluster head. We have also proposed to use gateway nodes in each cluster to enable the cluster head to reduce its transmission radius within the cluster to achieve better power saving. We analyze and compared the proposed algorithm along with the LEACH, LEACH-c and MIMO the most recent extend over the LEACH and show that the proposed algorithm can prolong the lifetime of the network.
