| Description |
Rapidly developing wireless technologies draw attention of many scientists, but still need to formalize the terms and concepts, as the differences between the varieties of wireless networks are not always obvious. Both MANETs (Mobile Ad-hoc Networks) and WSNs (Wireless Sensor Networks) are autoconfigurable networks of nodes connected by wireless links, where resources are scarce, and where traditional protocols and networking algorithms are inadequate. However great care should be taken before applying algorithms, protocols, and techniques to WSNs, if they were originally developed for MANETs. Although both types of networks indeed have many similarities, the differences are such that WSN can probably be considered a whole different research field. The paper provides a comparative analysis of two modern mobile network technologies - mobile self-configuring networks (MANET) and wireless sensor networks (WSN). Structural differences, differences in the principles of interconnectivity, in the degree of mobility and application domains were revealed. A protocol stack for WSN is similar to the one used in MANET networks and based on TCP/IP stack used in local networks, except for the addition of power, mobility, QoS, safety and task management planes that operate across all layers. This layered approach has remained accepted and mostly untouched in MANET networks for a quite long time, but there are serious difficulties to adhere to it in WSN. The main arguments for this opposition are that WSN is very application-specific and resource-constrained, so a layered architecture is shifting to flexible protocol architecture. All differences cause the creation of new approaches to the development of communication protocols and distributed algorithms. Among this new requirements are: • to easily integrate advanced protocol concepts and new communication paradigms, e.g. data centricity, • to provide flexibility enough to allow the system to be configured for various application requirements by selecting appropriate protocols and service functions, • to provide a system infrastructure to allow efficient operation of the protocols through crosslayer interaction, • to allow wireless sensor nodes and networks to adapt their behavior to environmental conditions, • to offer enhanced functionality support required for many applications, e.g. localization. Стремительно развивающиеся технологии беспроводной связи обращают на себя пристальное внимание ученых, но все еще требуют формализации терминов и понятий, поскольку различия между разновидностями беспроводных сетей не всегда очевидны. В статье выполнен сравнительный анализ двух современных мобильных сетевых технологий - мобильных самоорганизующихся и беспроводных сенсорных сетей. Названы их сходные черты. Выявлены конструктивные различия, а так же различия в принципах межсетевого взаимодействия, в степени мобильности и областях применения. Названные различия обусловливают создание новых подходов в разработке коммуникационных протоколов и распределенных алгоритмов. |
