In order to effectively solve the problem of routing efficiency in wireless sensor networks, a new chained routing algorithm based on group perception is proposed in this paper. First, the performance index parameters such as energy consumption and area coverage are given. Meanwhile, a chained routing strategy based on node utility value is established, which combines the “storage-carrying-forwarding” opportunistic transmission mode and decides whether a message needs to be forwarded to an encounter node according to a message forwarding strategy. Finally, the key factors affecting the chained routing algorithm are studied through simulation experiments. The results show that compared with random routing, the chained routing algorithm has great advantages in message delivery rate, collision probability, accuracy, etc.

Design of wireless sensor network routing protocol is still a problem that should be solved quickly. Although there are many achievements in this field, they all focus on single one property of WSN( Wireless Sensor Network) such as delay, hop count, energy consumption and so on. Dealing with the distinctive features of wireless channel, a routing strategy named MHRR( Minimum Hop Routing algorithm with Reliability assurance) based on AODV is proposed. Firstly, this paper provides a method which preserves multiple optimum routes by broadcasting and responding data frame; secondly, a routing filter mechanism is proposed to enhance the reliability of the network. At last, the optimum route can be chosen by specific factor in different situations. Experiments show that MHRR strategy is competent to deal with dynamic and bandwidth constrained WSN in reliability and delay.

In recent years, Wireless Sensor Networks (WSNs) have been promising approaches for a variety of application monitoring and capturing the required data from the environment. Due to the restricted communication range and high density of sensor nodes, routing in WSNs has been considered an important field of research over the past decade. The most popular protocol for clustering in WSNs is Low Energy Adaptive Clustering Hierarchy (LEACH) which is based on adaptive clustering technique. The factors affecting LEACH efficiency include Cluster Head (CH), topology structure and routing algorithm. This paper provides in the past years the taxonomy of various clustering and routing techniques based on LEACH in WSNs. The paper highlights the primary principle of each improved protocol and emphasize on their advantages and disadvantages compared to the LEACH.

In modern conditions of development, financial security is an integral part of the overall security of the region and is formed on the basis of the functioning of the financial system. The complication of relationships between key segments of international financial markets, as well as the limited ability to accurately predict future trends in the development of the global financial system, lead to a gradual increase in the risks that accompany the activities of economic entities, and an increase in the number and scale of internal and external threats that have a negative impact on the financial security of the state. This formulation of the issue requires generalization of approaches to determining the financial security of the region in order to further formalize this issue and determine the key factors affecting it. The article considers the types of financial security, as well as certain areas of ensuring the financial security of the region and their priority. In work the assessment of the level of socio-economic development of the region with a view to ensuring financial security on the basis of which offers the main activities and priority areas of implementation of the investment policy that will ensure financial security of the Republic of Crimea.
