DESIGN ISSUES AND CLASSIFICATION OF WSNS OPERATING SYSTEMS

Issues in Extensible Operating Systems

Operating systems research has traditionally consisted of adding functionality to the operating system or inventing and evaluating new methods for performing functions. Regardless of the research goal, the single constant has been that the size and complexity of operating systems increase over time. As a result, operating systems are usually the single most complex piece of software in a comput...

Issues in Evolving Existing Commercial Operating Systems

Modern commercial operating systems often have millions of lines of code, are highly non-modular, predominantly use C and assembly as implementation languages, are extremely time consuming to debug and have customers who often demand bug compatibility between releases. Introducing a completely new OS is essentially impossible not even Microsoft can do that with any degree of ease. However, supp...

Reliability Issues in Distributed Operating Systems

Distributed systems span a wide spectrum in the design space. In this paper we will look at the various kinds and discuss some of the reliability issues involved. In the first half of the paper we will concentrate on the causes of unreliability, illustrating these with some general solutions and examples. Among the issues treated are interprocess communication, machine crashes, server redundanc...

Performance Issues for Multiprocessor Operating Systems

Research Issues in Distributed Operating Systems

As distributed computing becomes more widespread, both in high-energy physics and in other applications, centralized operating systems will gradually give way to distributed ones. In this paper we discuss some current research on five issues that are central to the design of distributed operating systems: communications primitives, naming and protection, resource management, fault tolerance, an...
