Designing an efficient routing protocol that opportunistically forwards data to the destination node through nearby sensor nodes or devices is significantly important for an effective incidence response and disaster recovery framework. Existing sensor routing protocols are mostly not effective in such disaster recovery applications as the networks are affected (destroyed or overused) in disasters such as earthquake, flood, Tsunami and wildfire. These protocols require a large number of message transmissions to reestablish the clusters and communications that is not energy efficient and result in packet loss. This paper introduces ODCR - an energy efficient and reliable opportunistic density clustered-based routing protocol for such emergency sensor applications. We perform simulation to measure the performance of ODCR protocol in terms of network energy consumptions, throughput and packet loss ratio. Simulation results demonstrate that the ODCR protocol is much better than the existing TEEN, LEACH and LORA protocols in term of these performance metrics.

Appealing to the resource-based view and the resource advantage theory, this research aims to ascertain the complementarity of entrepreneurial and market orientation in enhancing the performance of small and medium enterprises.

Following a survey design, a self-administered questionnaire containing scales adapted from leading previous studies was used to collect data from 400 executives working in small and medium enterprises in Pakistan. Partial least squares-based structural equation modeling was performed to analyze the measurement and the structural models and test the significance of the hypothesized relationships.

It has been found that market orientation and entrepreneurial orientation enhance firm performance directly and indirectly with marketing capabilities and competitive strategies (partially or fully) mediating these causes and effects relationships.

The study adds to the literature on entrepreneurship, marketing and strategy and has significant ramifications for managers and public policymakers desiring to boost the performance of small and medium enterprises, which is crucial to the economic growth of developing nations, through nurturing and leveraging intangible resources such as market orientation, entrepreneurial orientation and marketing capabilities.

It is one of the rare attempts to investigate the complementarity of entrepreneurial orientation and market orientation, channeled through marketing capabilities and competitive strategies to boost SME performance, that too in the context of a developing country.
